Question

Define Raoult’s law for non volatile solute solution. Give its mathematical form.

Answer 1

The relative lowering of vapour pressure of a solution is equal to the mole fraction of the solute. The vapour pressure of a solution of a non-volatile solute is equal to the vapour pressure of the pure solvent at that temperature multiplied by its mole fraction.

Answer 2

the raoult's law state that, "the vapour pressure of solvent over the solution is equal to the vapour pressure of pure solvent multiplied by its mole fraction in the solution."
