How much does this guy know honestly? He has playlists for various subjects! I wonder if I honestly will ever be as smart as he is now.

I like how he always does his videos always assuming the learner is a beginner

always happy to see the infamous black background with the digital writing whenever i look up a topic i need help with, i know im in good hands

This was an amazing video and allowed me to help my daughter with some of her chem2 homework. Love math, especially when it is explained so well. Thanks again. Life saver.

you made it look so easy! I'm glad I found this video. It helped me with my homework, Thank you very much.

just another life saving video

before this video I was 0 and know I am 100% thank u bro god bless you

I literally can't thank you enough 😫

Such amazing lesson within 10minutes awesome

Thank you so much

Thank you so much.

Excellent teacher

you are great. i want to ask you to make a video about the reverse osmosis

you the man homedog

I think units are in L/mol (Time 4:35) You should divide by one to get proper units (mol/L)

In another video you made, you did the same exact question but there is a part you did differently here. When you obtained 0.6248M, in the other video, you divided it by the Liters. In here, you multiplied them. How do you know when to do that? Note: I calculate my conversions (g to M, mL to L) separately.

Hi just in case you are still interested in this, I think the solution from this video is correct, I did a similar mistake as you said in another video, its just because of the wrong interpretation of M=c/v. hope this explanation could help

Whats the Vant hoff factor of an unknown Polymer? I was given the grams of the polymer, liters of solution, osmotic pressure, and temperature.

How can you calculate the temperature if the only given is the mass of the solute?

One question pls But I saw it in one textbook where the ideal gas constant R was expressed in as 8.314J/mol.k Is that also right?

It depends on what you're calculating. They are both correct but just be careful with units because if you are calculating atm (atmospheres) then you cannot use that one with Joules.

In this video you had taken (I = 1) for NaCl while (I = 3) for MX2.. Will you please explain it clearly.. Secondly is there any instrument to measure Osmotic Pressure. Will you please elabora

i of NaCl is 2

why didnt you use the osmotic coefficient in the equation?

Where did you get 0.08206

@rvg_2483

it's the gas constant it is already given

its r, a constant. r= 0.08206

But who was HIS organic chemistry tutor...

can you come teach my chemistry lecture

why don't you distinguish between the M for molarity and the M for molar mass? looks the same. hell the m for mass is hardly distinguishable

@@samsrocky i always denoted my Ms differently so that I didn't have to struggle with it, at least on my own piece of paper. you'd *think* this would be standard practice... but it seems chemists are only interested in making things more difficult when possible.
