THAT'S IT????? My professor made this waaaaaay more complicated. Thanks!

what is an osmole ???

I couldn't have asked for a better explanation! You guys are great!

Thank you. So simple.

I really appreciate the way you broke this down

Amazing!! Thank you

Dammit, I love you guys. You make my college Physiology professor (an MD) so unbelievably irrelevant.

Great video!

I got it, thanks :)

thanks !

Oh, I've never studied this before, but thank you!

thank you!

Thank youu so much 😭

i love this sm

from this, could it be that osmolarity is the total of the moles from solutes when we put them in the cells and try to find out the total of it since they could not go into plasma easily??

It was wonderfully explained ❤️

Yes, it was.

so Osm always refers to the dissociated state?

Mole =gram molecular weight while osmole =gram molecular weight of osmotically active solute In 1 mole of glucose we have 1 avagadros no of osmotically active particle while in 1 mole of Nacl we have 2 avagadros no of osmotically active particles

What’s your problem with Nitrogen bro 🤣🤣🤣🤣 Do you want to be Cool 😎 as hell

thanks for your perfect explanation, i have a question, why for NaCl, we separated, na+, and CL- but for glucose or urea we know them as 1 molecule?

glucose and urea don't dissociate in water

NaCl is ionic in nature and can dissociate, or split into Na+ and Cl- ions in water( water is ionic too, and we say like dissolves like) while glucose and urea are organic molecules and would not break up like NaCl does.

In the example, it's not molarity but molality I should say......

So it means that osmolarity is molarity of different solutes in one liter solution.

Hello, I have a question about this. The denominator of Molarity should be the solution, so how can it be calculated by 1 liter of water?

I didn't get that

Your video was good but you write the formula of Urea wrong.

so after seeing that im thinking there is no difference between osmolarity and molarity so why the word osmolarity in the first place

There's a difference. If there weren't any then why would there be difference in molarity and osmolarity of NaCl??Ask yourself

@@padmanabhashetty4263 bcos nacl is one mole but when you wanna calculate osmoles of nacl it get dissociated to Na+ and cl- so its 2 osmoles

At 4:00 it seems to me that he is making a mistake in calculating the molarity. When you add those solutes to 1 liter of solvent, the resulting solution will no longer be 1 liter, so the denominator fractions in the molarity calculation should not be exactly 1 liter. For example, 1 mole of glucose has a mass of 180g and the density of a 1 molar glucose solution is still close to 1 g/mL (1.066 g/mL). 1 liter of this solution has a mass of 1066 g but only 886 g of it is water, so it would have to be made up from about 890 mL of water. Another way to say this is that if you begin with 1 liter of water and add 1 mole of glucose, you will get 1180 g of solution whose volume will be 1.1 liters and therefore its molarity will be 0.9, not 1.0.

You forgot that during the time it took for all the solutes to dissolve, some water evaporated, thus cancelling out the added amount.

When you dissolve solute in a solvent, it only increases the mass of the solution but the volume does not change.

@sbreheny

That is not true in general. The volume may change.

You must be kidding. The evaporation will not be significant and certainly not magically always equal to the change in volume from adding a solute. Besides, evaporation would change the mass, too.

@perikaveera

Volume will change only after supersaturation point for that particular solvent. And the evaporation will be negligible considering this is a lab experiment done quickly, not over hours or days

I was surprised by the poor explanation for this one.

Poor say the concept simply

doesnt really explain the concept of osmolarity. Im not sure he actually understands it.
