STEP 1: Convert Input(s) to Base Unit

Weight of Solute: 21 Gram --> 0.021 Kilogram (Check conversion here)
Molecular Mass Solvent: 18 Gram --> 0.018 Kilogram (Check conversion here)
Vapour Pressure of Pure Solvent: 2000 Pascal --> 2000 Pascal No Conversion Required
Vapour Pressure of Solvent in Solution: 1895.86 Pascal --> 1895.86 Pascal No Conversion Required
Weight of solvent: 20 Gram --> 0.02 Kilogram (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

M_solute = (w*M*p_o)/((p_o-p)*W) --> (0.021*0.018*2000)/((2000-1895.86)*0.02)

Evaluating ... ...

M_solute = 0.362972921067793

STEP 3: Convert Result to Output's Unit

0.362972921067793 Kilogram -->362.972921067793 Gram (Check conversion here)

FINAL ANSWER

362.972921067793 ≈ 362.9729 Gram <-- Molecular Mass Solute

What causes the Relative Lowering Of Vapour Pressure?

This lowering in vapour pressure is due to the fact that after the solute was added to the pure liquid (solvent), the liquid surface now had molecules of both, the pure liquid and the solute. The number of solvent molecules escaping into vapour phase gets reduced and as a result the pressure exerted by the vapour phase is also reduced. This is known as relative lowering of vapour pressure. This decrease in vapour pressure depends on the amount of non-volatile solute added in the solution irrespective of its nature and hence it is one of the colligative properties.
