SOLVED: A solution is 40.0% by mass benzene (molar mass 78.113 g/mol) in carbon tetrachloride (molar mass 153.823 g/mol) at 20.0 °C. The vapor pressure of pure benzene is 74.61 mmHg and pure carbon tetrachloride is 91.32 mmHg at this temperature. What is the vapor pressure of this solution at this temperature?What is the mole fraction of benzene in the vapor above the solution at this temperature?

The molar volume of liquid benzene ( density = 0.877 g ml^-1 ) increases by a factor of 2750 as it vaporizes at 20^∘ C and that of liquid toluene ( density = 0.867 g ml^-1 )increases by a factor of 7720 at 20^∘ C. A solution of benzene and toluene has a vapour pressure of 46.0 torr. Find the mole fraction of benzene in the vapour above the solution:
