For a dilute solution, Raoult's law states that

the lowering of vapour pressure is equal to the mole fraction of solute

the relative lowering of vapour pressure is equal to mole fraction of solute

the relative lowering of vapour pressure is proportional to the mass of solute in solution

the vapour pressure of the solution is equal to the mole fraction of solvent

Text Solution

Verified by Experts

The correct Answer is:
