Which does not change on dilution?
Molarity of solution
Molality of solution
Milli-mole and milli- equivalent of solute
Mole fraction of solute

The relative lowering of vapour pressure of a solvent by the addition of a solute is : 1) proportional to the molarity of the solution 2) proportional to the molality of the solution 3) equal to the mole fraction of the solute 4) equal to the mole fraction of the solvent.
