Calculate the freezing point of a solution of 165 g of

Question

Calculate the freezing point of a solution of 1.65 g of naphthalene (C₁₀H₈) in 15.90 g of benzene. 

The freezing point of pure benzene is 5.5°C. 

K_f = 5.12°C kg/mol.

Calculate the boiling point of the above solution. 

The boiling point of pure benzene is 80.1°C. 

K_b = 2.53°C kg/mol.
