We can calculate ∆Tb and ∆Tf from the equations:

∆Tb = Kbb

∆Tf = Kfb

where Kb and Kf are the molal boiling point elevation constant and the molal freezing point depression constant, respectively, and b is the molality of the solution in mol/kg.

pairing: student! gojo x reader

summary: to you, chemistry means two things – the worst subject on earth and the best feeling ever. satoru somehow teaches you both.

word count: ~2.0k

notes: suggestive. modern au. mentions of organic chemistry. making out. guest appearance by geto. gojo calls you 'smart girl' at one point. rushed. barely proofread. written while i was half asleep. like always, reblogs are very very appreciated.

a/n: i genuinely don't know how i feel about this one... there are parts i like and parts i don't like (that i was too lazy to fix) and it's kinda just stitched together ... lmk what you think in the comments pretty pls 💞

"question four – what's the difference between molarity and molality?"

"wait, those are two different things?"

since you and satoru had both procrastinated studying for your impending chemistry test, you found yourselves at the library long past midnight. 

it was an accident – when you had decided to study in the library instead of at home, you hadn't anticipated running into anyone you knew. but of course, satoru gojo, the charismatic guy in your english class, was here too. 

you wouldn't say that the two of you were close – acquaintances was a better word. satoru and you knew of each other and were on friendly terms, but until now you had never really taken the time to talk alone.

but hey, just because you didn't know the guy that well didn't mean you were about to turn down a free study partner. especially one as attractive as satoru, although it was admittedly a bit distracting when you were trying to focus on your work.

it wasn't his fault – his long, white lashes were just naturally mesmerizing. and his eyes? breathtaking. even in the dim light of the library, his eyes shone like crystals. you didn't even want to start thinking about his hands, his jawline, and certainly not his body, otherwise you'd be studying something else the whole night – him and his stupidly attractive self.

after a ton of mental self-chiding, you finally manage to get your priorities straight and actually try to study, but what started as a study session gradually turned into a tutoring session when you two realized that one of you needed a lot more help than the other.

and to your dismay, that was you.

"you really thought molarity and molality were the same thing?" satoru scoffs, shamelessly grinning. "y'know, it's really a miracle you have an A in the class. you don't deserve it."

"shut up," you reply, knowing only too well that he was right. the only reason you were able to maintain a good grade in this stupid chemistry class was because the teacher offered a ridiculous amount of extra credit.

but unfortunately, you couldn't float on that boat for much longer. your grade was still slowly slipping, from a 95 to a 93 to what was now a flat 90, and your pride wouldn't let that number fall any further.

satoru laughs and shakes his head, running a hand through his white hair. "c'mon, at least tell me what molarity is."

"uhh, that's moles per liter, right?"

he nods and twirls a pen in between his fingers. "yeah, that's right. now what's molality?"

"how should i know? i don't pay attention in class," you groan, resting your head in your palm.

satoru rolls his eyes, and you take a moment to appreciate how gorgeous they are. they were a color somewhere in between cerulean and ocean blue, further enhanced by his long white lashes.

your admiration quickly fades to indignation when satoru clicks his tongue and starts rattling off some dictionary definition of molality.

"y'know, you'd know more if you weren't on your phone the whole time in class," he says dryly. 

you groan again and lean back in your chair. "it's just so boringgg," you whine, pushing the chemistry worksheet away. "forget it, i'll just guess on the test tomorrow. it usually works."

as you start to sweep your pencils and papers into your bag, satoru grabs your wrist and gets you to meet his ocean-blue eyes. "i'll feel bad if you do badly because i didn't help you enough."

his grip on your wrist is firm but gentle as he leans a millimeter closer. "let me help you, yeah?"

after a beat of silence, you nod and look away. his glacial eyes are piercing in the kind of way that makes you think he can see right through you, and you don't like the feeling of being readable.

"so, am i gonna have to force you to pay attention or will you do it yourself?"

the question catches you off guard. something about the way he asks it makes it very clear that it's a genuine question – either you can try and make yourself focus or he can make you.

you don't quite know what the latter means, but it sounds more fun, so that's what you pick.

and that's how you ended up on his lap, hair wrapped around his fingers as he quizzed you from behind. 

satoru had somehow motivated you to actually try and study by rewarding you with a kiss for every question you got right. had the offer come from anyone else, you would've called them a creep, but satoru was attractive and he knew it. on top of that, he wasn't afraid to use his good looks to get what he wanted, which, in this case, was for you to do good on tomorrow's test.

"avogadro's number?"

"umm, 6.022 x 10 to the 23rd?"

satoru nods and kisses the side of your face, lips trailing over your jawline as his eyes flick back to where he'd scribbled a couple practice questions.

"how many bonds can hydrogen form?"

"one."

this time, his lips touch your neck, and it takes every ounce of self-restraint in your body to hold back the embarrassing sound you can feel at the bottom of your throat.

"last question, how many bonds can carbon form?"

this time, your voice comes out breathier than you expected. "four, right?"

"smart girl." 

and now, for the first time this night, he gives you a quick kiss on the lips. he doesn't linger and he doesn't give you any chance to savor the taste of his lips – one second his mouth is pressed to yours, the next it's moving with words you don't quite absorb.

he rifles through a couple papers and makes a face. "actually, my bad, there's more. not much," he quickly adds when he sees you groan. "just some stuff we didn't cover completely at the beginning."

"you're the worst."

"you'd fail without me."

"maybe, but at least i'd be happier."

despite your playful jabs, the truth that studying with satoru was a lot more bearable than studying by yourself, and it was also a lot easier to stay awake. before you knew it, two hours came and went, and you were practically an expert on everything that could possibly be on the test tomorrow.

and when you're finally able to confidently tell satoru the difference between molarity and molality, that's when he turns you around on his lap to face him and presses his lips to yours again, and this time, he doesn't pull away.

"you're a quick learner, aren't you?" satoru mumbles against your lips. he pulls back for a second to get some air before grabbing your chin and leaning in for more. "yeah, i wonder what else i could teach you. you wanna find out, pretty?"

you're not entirely sure when the studying ended and the making out started, but you certianly do know when the making out ended. 

before you could reply to satoru's rather suggestive question, a message blared from the speakers around the library and interrupted whatever you two had going on.

" it is now closing time. all remaining students, please return to your residential places immediately."

satoru chuckles and nudges you off of his lap before standing up and stretching. "well, it's almost 3, we should get some rest." 

"yeah, that's probably smart."

"of course it is. i'm smart."

"yeah yeah," you mumble after a second when no better retort comes to mind. probably because he was telling the truth – satoru was smart, and he knew it. 

"well, i'll see you tomorrow," he says, sweeping the remainder of his stuff into his backpack before slinging it over his shoulder. "good luck on the test, you'll do great."

you smile and zip up your own backpack before heading towards the exit on the other side of the library, his words buzzing around your head and the memory of his mouth fresh on your lips the whole way home.

"satoru, satoru! guess what i got on my test!"

after you made your way home from the library last night, you slept like a rock. barely a minute after you tiredly stumbled into your oh-so welcoming bed, you were out. 

despite only getting around five or six hours of sleep, you felt pretty damn good the next morning as you sat down to take your chemistry exam. and that good feeling stayed with you the whole test, and when you finished, you were able to confidently set your paper on your teacher's desk.

well, as confidently as anyone could set a piece of paper down anyways.

but now it was lunchtime, and a soft chiming sound from your phone signaled that the test was score and put into your grade. your hands shook slightly as you tapped the notification, but to your delight, a 97 lit up your screen.

and of course, who else could you credit with this besides satoru? so you walked over to where you'd seen him hang around during lunch and called out his name, but you really hadn't anticipated company.

"ah, satoru, who's this?" the dark-haired boy beside satoru asked, voice light with interest. "have you been seeing someone and not telling me about it?"

satoru laughs and shoves the guy's shoulder before turning to you and grinning. "sorry 'bout him. yeah, what was your score?"

he has a lollipop in his mouth, and as he raises an eyebrow at you, you feel yourself grin as you proudly say "a ninety seven! my grade went up to the mid-ninties, too!"

"smart girl. knew you could do it," satoru says, a lopsided smile spreading across his face.

"it's only 'cause of you," you say, a bit sheepishly. "without your help, i wouldn't've been able to do that."

satoru exhales a laugh and reaches out to ruffle your hair. he looks like he's about to say something before the other guy clears his throat.

"sorry to interrupt your... moment, but the lunch line is starting to grow and my patience is starting to shrink. satoru, you coming?" 

"yeah, give me a sec, suguru." 

satoru looks back down at you, sunglasses resting on the tip of his nose and cerulean eyes flashing in the sunlight. "looks like i gotta go."

you nod and wave him off. "yeah, i'll see you around, i guess. thanks so much for the help, really. i owe you one."

satoru grins and pulls the lollipop out of his mouth. still looking at you intently, he runs his tongue over the lollipop one last time before sticking in your mouth.

"you wanna pay me back for tutoring you last night?" satoru asks, smirking at the surprised look on your face. "drop by my place tonight. i'll teach you something else this time."

he leans in and gives you a quick, sugary kiss before turning away and walking in the direction geto left in, leaving you with nothing but a tingling sensation in your lips and a promise to see you soon.

satoru laughs to himself as he walks away, waving one hand back at you without bothering to turn around. when he catches up to suguru, the latter notices the wide smirk satoru dons and asks about it.

"oh, it's nothing. just looking forward to tonight."

you were, too.

a/n: if i wrote smut i'd write a pt 2 to this. maybe one day idk

i'm probably going to get back to writing some more angst after i finish the last of my requests. i miss writing fics that make people cry /hj

There's a special spot in hell for scientists who make similar sounding terminology, especially when they're things that would regularly be used with each other but mean completely different things. Like molarity and molality (italicized to show my contempt).

Forget the invention of weapons of mass destruction, that's the most evil thing a scientist has ever done

december 4, 2023 - monday week 2

saw a campus cat on the way to chapter today!!

i was also taken by surprise by a quiz in bioanalytical chemistry (and learned that i had missed a homework since it wasn't in the calendar of our main software), so... off to quite the start there. i've almost finished the homework, though, and i got a B on the quiz, so not all is lost!

my physical chemistry professor is also really funny - last term, our prof was very insistent on always using correct units and significant figures and all that, but our current prof is much more flippant. "at low concentrations, molarity and molality are basically the same. and density doesn't ever change"

hopefully getting to sleep pretty early tonight! let's get a good start to the week.

Molarity Converter: Simplifying Complex Chemical Conversions

In chemistry, it is often necessary to convert between different units of concentration to maintain consistency and accuracy across experiments. Whether you're working in a research lab or studying for your next chemistry exam, performing conversions between molarity and other concentration units can be complex and time-consuming. Thankfully, a molarity converter helps simplify these conversions, providing accurate results in seconds.

In this article, we'll explore the importance of unit conversions in chemistry, the common challenges faced, and how the molaritycalc.com molarity converter makes chemical conversions easier and more efficient.

Why Unit Conversions Matter in Chemistry

Chemistry is a discipline that frequently involves working with solutions of varying concentrations. Depending on the experiment or the field of study, chemists use different units of concentration, such as molarity, molality, mass percent, or normality, to express the quantity of solute dissolved in a solvent.

These conversions are essential for comparing solutions or preparing specific concentrations for experiments. For example:

Molarity (M) measures the concentration of a solute in a given volume of solution, expressed in moles per liter.

Molality (m) measures the concentration of a solute in terms of moles per kilogram of solvent.

Mass percent expresses the mass of the solute as a percentage of the total mass of the solution.

Each of these units provides valuable information for different types of experiments. However, when working with multiple solutions or when translating data between fields, it becomes necessary to convert between these units. Without a tool to automate the process, these conversions can become confusing, leading to errors that could impact experimental results.

The Challenges of Manual Conversions

For many chemistry students and professionals, performing these unit conversions manually is one of the most challenging and error-prone aspects of their work. Here are some common challenges that people face:

Complex formulas: Each unit of concentration requires a different formula for conversion. For example, converting molarity to molality involves knowing both the molarity and the density of the solution. The formulas themselves can be complicated, especially for someone who is new to chemistry or dealing with multiple solutions.

Time-consuming calculations: Converting between units like molarity, molality, and mass percent often requires multiple steps. This takes time and can slow down experimental progress, especially when working with large datasets.

Human error: With so many variables in play, it's easy to make a mistake during a manual conversion. Even a small error in calculations can throw off the results of an entire experiment or analysis.

These challenges underscore the importance of having a reliable and efficient molarity converter to simplify the process.

How the MolarityCalc Molarity Converter Simplifies Chemical Conversions

The molaritycalc molarity converter is specifically designed to make unit conversions fast and accurate. Whether you're converting molarity to molality, mass percent, or any other unit of concentration, the molarity converter can handle it all in just a few simple steps.

Here’s how the molarity converter on molaritycalc works:

Select the type of conversion: Begin by choosing the type of conversion you need. For instance, if you're converting from molarity to molality, you'll select this option from the dropdown menu on the calculator.

Input the required data: Depending on the conversion type, you'll need to input different values, such as the molarity, density, or mass of the solution. The molarity converter guides you through the input fields to ensure you enter all necessary information.

Instant conversion: After entering the data, click the "Convert" button, and the molarity converter will instantly provide the converted concentration in the desired unit. This eliminates the need for manual calculations and ensures that your conversions are accurate.

With molaritycalc, chemists and students can convert between different units of concentration quickly and with confidence, allowing them to focus on conducting experiments and analyzing results rather than spending valuable time on conversions.

Example: Converting Molarity to Molality in a Salt Solution

Let’s walk through a common conversion that researchers often encounter—converting molarity to molality in a salt solution. Suppose you're working with a sodium chloride (NaCl) solution that has a molarity of 2 M, and the density of the solution is 1.05 g/mL.

To convert molarity to molality, you would follow these steps using the molaritycalc molarity converter:

Input the molarity: In this case, 2 M.

Enter the density of the solution: 1.05 g/mL.

Calculate the molality: The molarity converter will automatically calculate the molality based on the input data.

The molarity converter provides the result in seconds, giving you the molality of the sodium chloride solution without requiring you to manually work through the complex formula.

Benefits of Using a Molarity Converter

The molaritycalc molarity converter offers several benefits for both students and professional chemists:

Accuracy: The molarity converter ensures that your conversions are precise. This reduces the risk of errors that could impact the outcome of experiments, especially when working with solutions of high or low concentrations.

Speed: Manual conversions take time, especially when working with multiple solutions or datasets. The molarity converter speeds up the process by providing instant results, allowing you to focus more on the experimental work itself.

Flexibility: The molarity converter can handle a wide range of conversions, from molarity to molality, normality, mass percent, and beyond. This versatility makes it useful in a variety of chemical fields, whether you're working in academic research, pharmaceutical development, or environmental analysis.

Ease of Use: The simple, intuitive interface of molaritycalc makes it easy to input the necessary data and perform conversions, even if you're new to chemistry or unfamiliar with the formulas.

Common Unit Conversions in Chemistry

Chemists frequently encounter several types of unit conversions, and having a tool that can handle these conversions is invaluable. Here are some common examples:

Molarity to Molality: This conversion is useful when working with solutions of varying concentrations and densities. Molality is often preferred in experiments involving temperature changes because it does not depend on the volume of the solution, which can fluctuate with temperature.

Molarity to Mass Percent: This conversion is essential when you need to express the concentration of a solution as a percentage of the total mass. Mass percent is particularly useful in industrial chemistry, where large quantities of chemicals are used.

Normality to Molarity: Normality (N) expresses the concentration of reactive units in a solution. It is often used in acid-base reactions and redox reactions. Converting between normality and molarity is necessary when comparing solutions or standardizing reactions.

Dilution Calculations: In many cases, chemists need to dilute a solution to a lower concentration. Using a molarity converter allows you to calculate the final molarity of the diluted solution quickly and accurately.

By using the molaritycalc molarity converter, you can perform all of these conversions and more with just a few clicks.

Conclusion

Unit conversions are a fundamental part of chemistry, and performing these conversions manually can be both time-consuming and prone to error. The molaritycalc molarity converter simplifies these conversions, allowing chemists and students to quickly and accurately convert between different units of concentration.

Whether you're converting molarity to molality, mass percent, or any other concentration unit, molaritycalc makes the process easy and efficient. By incorporating this tool into your chemical research or studies, you can save time, reduce errors, and improve the accuracy of your experimental work.

With the molaritycalc molarity converter at your disposal, complex chemical conversions are no longer a barrier to successful experimentation.

Shocking new documentation from October 7th shows the abduction and horrifying execution of 21-year-old Tanzanian student Joshua Luito Molal. After that, they also kidnapped his body, which has been kept in Gaza ever since, and only recently it became known that he was not alive at all. He is not even an Israeli citizen, his only sin was being in Israel at that moment. As far as these terrorists are concerned, every Israeli and every person in the world who recognizes the State of Israel should be slaughtered!

If you are not horrified at the above video, if you can excuse it in any way, please take BLM out of your bio. Black people's lives don't matter to you. I'm not sure that they ever did.

Stupid thing but it's so silly how in chemistry M is the symbol for molar mass and M is shorthand for the unit mol ℓ⁻¹ of molar concentration. Also the times my dyslexic ass has misread molality as molarity or vice versa is crazy.
