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?

SOLVED: How much energy must be removed from a 94.4 g sample of benzene (molar mass = 78.11 g/mol) at 322.0 K to solidify the sample and lower the temperature to 205.0 K? The following physical data may be useful: AHvap = 33.9 kJ/mol, AHfus = 9.8 kJ/mol, Cliquid = 1.73 J/g°C, Cgas = 1.06 J/g°C, Csolid = 1.51 J/g°C, Tmelting = 279.0 K, Tboiling = 353.0 K.
