Question
0.0821 kg of biphenyl (C12H10) is dissolve in benzene (CHo) to create a
solution with a total volume of 350.0 mL. (Assume the change in volume
is negligible)
a) What intermolecular forces are shared between biphenyl and benzene?
b) 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)
c) 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)
d) What would be the osmotic pressure (in atm) of this solution at 40.0 °C?
Assume the density of the solution is the same as benzene, 0.877 g/mL.
