Calculate the freezing point of a solution of 3.46 g of a compound, X, in 160 g of
benzene. When a separate sample of X was vaporised, its density was found to be
3.27 g/L at 116°C and 773 torr. The freezing point of pure benzene is 5.45°C, and
Kf is 5.12°C kg/mol.

Calculate the freezing point and boiling point of a solution containing 15.8 g of naphthalene (C10H8) in 115.0 mL of benzene. Benzene has a density of 0.877 g/cm3.

a. Calculate the freezing point of a solution. (Kf(benzene)=5.12∘C/m.)

b. Calculate the boiling point of a solution. (Kb(benzene)=2.53∘C/m.)
