Why vapour pressure of a liquid decreases when a non - volatile solute is added to it ?

Vapour pressure of a solution containing a non volatile solute is

Vapour pressure of solution of a non-volatile solute is always

At 20^@C , the vapour pressure of diethyl ether is 442mm. When 6.4g. of a non-volatile solute is dissolved in 50g. of ether, the vapour pressure falls to 410mm. The Molecular weight of the solute is

V.P. of solvent in pure state is 600 mm Hg, when a non-volatile solute is added to it vapour pressure of solution becomes 594 mm Hg, then x_(B) will be
