On dissolving 0.5 g of non-volatile, non-ionic solute to 39 g
Question

On dissolving 0.5 g of non-volatile, non-ionic solute to 39 g of benzene, its vapour pressure decreases from 650 mm of Hg to 640 mm of Hg. The depression of freezing point of benzene (in K) upon addition of the solute is __________.
(Given data: Molar mass & molar freezing point depression is 78 g \displaystyle{m}{o}{l}^{{-{1}}}&{5.12}{K}{k}{g}{m}{o}{l}^{{-{1}}}]
