Benzene (C6H6; molar mass = 78.11 g/mol) and toluene (C7H8; molar mass = 92.13 g/mol ) form an ideal solution. Suppose that a mixture is composed of 65.0 g of benzene and 75.0 g of toluene. (a) Calculate the mole and mole fraction of benzene in the mixture . (b) Calculate the partial vapor pressure of benzene and toluene, respectively, at 25oC. (c) What is the mole percent of benzene in the vapor at 25oC? (The vapor pressure of pure benzene and toluene at 25oC are 95.1 torr and 28.4 torr, respectively).
