9. Benzene freezes at 5.42°C and boils at 80.1°C. Its heat of vaporization at the boiling point is 95.46 cal/g. A solution containing 12.8 g of naphthalene in 1000 g of benzene freezes at 4.918°C. Define,
a) At what temperature will this solution boil?
b) what is the vapor pressure over this solution at 80.1°C?
c) what is the specific heat of fusion of benzene?
