Question

A solution is made by dissolving 0.0887 kg of biphenyl (C₁₂H₁₀) in 350.0 mL of benzene (C₆H₆).

a. If the boiling point of pure benzene is 80.1 °C, then what would be the boiling point of this solution in °C? (Kb for benzene is 2.53 °C/m and the density of benzene is 0.877 g/mL)

b. If the vapor pressure of pure benzene is 24.4 kPa at 40.0 °C, then what will the vapor pressure of the solution be in kPa? (Consider biphenyl to be nonvolatile and the density of benzene is 0.877 g/mL)

c. What would be the osmotic pressure (in atm) of this solution at 40.0 °C? (The density of benzene is 0.877 g/mL.)
