Relative lowering of vapor pressure because of a non-volatile solute is equal to the mole fraction of the non-volatile solute in the solution.
From the given data: Mole fraction of the solute (assuming no assosiation/disassosiation) = RLVP = 0.025.
Assuming the solution to be binary mole fraction of solvent = 1 – mole fraction of solute.
Hence, mole fraction = 1 – 0.025
