Distillation on a mixture of benzene and toluene is performed. As the in the initial distillate is being collected, you observe the boiling point of the mixture to be 89.5 C. Given the vapor pressures of benzene and toluene (Benzene=1000 mm Hg and Toluene=400 mm Hg). What is the percent composition of benzene and toluene respectively in the mixture? What is the composition of the initial distillate assuming ideal mixture conditions?
