'W' g of a non-volatile electrolyte solid solute of molar mass 'M' g $$mol^{-1}$$ when dissolved in 100 mL water, decreases vapour pressure of water from 640 mm Hg to 600 mm Hg. If aqueous solution of the electrolyte boils at 375 K and $$K_{b}$$ for water is 0.52 K kg $$mol^{-1}$$, then the mole fraction of the electrolyte solute ($$x_{2}$$) in the solution can be expressed as
(Given : density of water= 1 g/mL and boiling point of water= 3 73 K)
