Vapour pressure of liquid solutions

The video tutorial explains the concept of vapor pressure using hot chocolate as an example. It describes how vapor pressure is measured with a manometer and discusses its behavior in solutions of volatile liquids. The tutorial covers Dalton's and Raoult's laws, relating vapor pressure to mole fractions, and compares Raoult's law to Henry's law. It also explores the vapor pressure of solutions with non-volatile solutes, emphasizing the impact of solute quantity on vapor pressure.

How can the total vapor pressure over a solution be determined?

Describe the relationship between vapor pressure and mole fraction according to Raoult's law.

What is the significance of the proportionality constant in Raoult's law?
