Benzene c6h6 and toluene c6h5ch3 form ideal solutions. At 35 degrees celcius the vapor pressure of benzene is 160. torr and that of toluene is 50.0 torr. In an experiment, 3.9 mol of benzene and 4.9 mol of toluene are placed in a closed container at 35 degrees celcius and allowed to cometo equilibrium. What is the mole fraction of toluene in the vapor phase?
