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

(B) According to Raoult's law for a solution containing a non-volatile solute,the relative lowering of vapour pressure is equal to the mole fraction of the solute present in the solution.Mathematically,it is expressed as: $\frac{P^o - P_s}{P^o} = x_2$,where $P^o$ is the vapour pressure of the pure solvent,$P_s$ is the vapour pressure of the solution,and $x_2$ is the mole fraction of the solute.
