Properties of solutions that depend on the
number of molecules
1. pressure lowering
2. boiling point elevation
3.freezing point depression
4. osmotic pressure
Vapor pressure :
The lowering of the vapor pressure of a solvent due to the presence of nonvolatile, non-ionizing solute is summarized by Raoult's law
“The vapor pressure of a solvent in an ideal solution is directly proportional to the mole fraction of the solvent in the solution”
