The vapor pressures of benzene and toluene at 95◦C are,
respectively, 155.7 kPa and 63.3 kPa. A gaseous mixture consisting
of 50 moles of benzene and 50 moles of toluene was cooled to 95◦C.
As a result of the cooling, some of the benzene and toluene
condensed. If the total pressure above the condensate was 101.3
kPa, calculate:
(a) the mole fraction of benzene in the condensate
(liquid).
(b) the mole fraction of benzene in the gas phase after cooling....
