A solution containing 55% benzene, 28% toluene and 17% xylene by weight is in contact with its vapor at 80C. Calculate: a. Total pressure of the system. b. Molar compositions in the liquid and vapor phases Assume ideal solution and ideal gas mixture. Antoine constants of benzene, toluene and xylene are listed below. The equation is of the form: where Pss is the vapor pressure in torr and T is in C. log10Ps=AT+CB Antoine Constants: Benzene: A=6.87987,B=1196.760,C=219.161 Toluene: A=6.95087,B=1342.310,C=219.187 Xylene: A=6.99053,B=1453.430,C=215.310
