A liquid mixture of benzene and toluene is contained in a closed vessel at 60°C. The only other component in the system is nitrogen gas which is used to pressurize the system to 1 atm total pressure (absolute). The liquid is 70 mole% benzene and 30 mole% toluene, and the N2 is considered non-condensable (i.e., the liquid mole fraction of nitrogen is zero). Consider the mixture to be ideal, and determine the vapor mole fractions of the three components. (Document any data that you use that is not given in the problem statement.)
