Raoult's Law - How To Calculate The Vapor Pressure of a Solution

This chemistry video tutorial provides a basic introduction into Raoult's law which says that the vapor pressure of a solution is the product of the mole fraction of the solvent and the partial pressure of the pure solvent at a given temperature. This video explains how to calculate the vapor pressure of a solution with a nonvolatile solute. It also explains how to calculate the mass of solute / glucose needed to reduce the vapor pressure of the solution to a certain value.

Rather than reading the textbook and looking at cluttered examples, I just watch his videos. Such a life saver the night before the test!

[georgeneighborhoods]

WTF, I always search for physics problems and you're always in the top of my search. Thank you.

[litchfirmian]

Why is the timing so perfect, my prof have just finished teaching this topic.

[ronielyncuison]

I would like to correct or point out a slight mistake in the last problem. Both sides should be divided by 0.9765. The answer would be 0.3338 moles.

Your channel is about to help me pass CHEM II in collage cause of how bad of a job my proffesor is doing. And guess what? He's the only one teaching the class so I can't even change teachers.

FANTASTIC concise explanation and the practice questions you chose were perfect at covering this topic. Thank you!

[deadbzeus]

You are the best! I appreciate all your work making all these videos, You are an amazing science communicator.

[jyotijangir]

this is making my study very easy thank you so much, the organic chemistry tutor

[jia-xuan-shuo]

You’re my life savor. Yet at 13’10”, I believe the denominator is supposed to be 0.9765. I made lots of similar mistakes.

Professor Organic Chemistry Tutor, thank you for a basic Introduction and explanation of Raoult's Law and how it's used to calculate Vapor Pressure of a Solution in AP/General Chemistry. Th example problems are awesome when it comes to calculating Vapor Pressure, however, there is an error in problem number three at the 13:01 minute mark. Professor Organic Chemistry Tutor, there is a division error in your calculation. Please correct this error in the video.

Why u post this the day after the exam that I needed this ;-; jk, great video!

[sparklecakes]

I wish that some of the questions weren't on patreon and the video too. I don't have any money lol

[PatrickPetro-ns]

Big up, God bless ue u had helped at a great extent

[sofyandiab]

thanks alot man, you're a life saver

[vaibhavimarathe]

thank you so much u have no idea how much this helped

[ghostveiwer]

Thank you man, you have saved the day 👍

[shivanireddy]

Why moles of ions? Can't we take no
Of moles of cacl2 directly?

[Gentleman]

If you can please answer. How do you know what to find when the question asks what the vapor pressure?

[meniscusmedical]

Slight error with the numbers sir. just 0.9765 and not 0.9675 but other than that thank you.

[mysciencecruise]

thank you so much. this is very helpful
