A) the lowering of vapour pressure is equal to mole fraction of solute
B) the relative lowering of vapour pressure is equal to mole fraction of solute
C) the relative lowering of vapour pressure is proportional to the amount of solute in solution
D) the vapour pressure of the solution is equal to the mole fraction of solvent
Correct Answer: B
