1

when you add solute

the vapour pressure decreases, the boiling point increases, the freezing point decreases and osmotic pressure lol

2

Henry's law

[gas]=Kh (constant) and P ( mole ratio of partial pressure of gas)

3

raoult's law

VP = X solvent VP solvent

4

boiling point elevation

delta Tb = iKbM

tb is regular- pure solvent
m= molality

5

freezing point depression

delta T= I kf m
tf is solvent-solution
m is molality

6

osmotic pressure

PI= iMRT

M is molarity
R= 0.08206
