Consider a mixture of 250 mL of benzene and 500 mL of toluene at room temperature.  Density of toluene is 867 kg/m 3 and of benzene 876 kg/m 3 and the saturated vapor pressure  v of pure toluene and benzene are 28.4 and 95.1 mmHg respectively at room temperature.
a. What is the total concentration of the liquid?
b. What is the molefraction of benzene and toluene in the mixture
c. What is the total vapor pressure of the mixture
d. What is the molefration of benzene in the air right above the liquid mixture assuming
the system is at room temperature and open to air?
e. What is the mole fraction of toluene in the air right above the liquid mixture?
