Answer:
The measurement of relative lowering of vapour pressure can be used to determine the molar mass of a nonvolatile solute. For this purpose, a known mass of the solute is dissolved in a known quantity of solvent. The relative lowering of vapour pressure is measured experimentally.
Relative molar masses can be determined by measuring colligative properties for a dilute solution of a non-ionized solute. ... As per this law, the relative lowering of the vapor pressure of a dilute solution is equal to the mole fraction of the solute present in dilute solution
