A liquid is a mixture of benzene (C6H6) and toluene (C7H8). The
sample contains 20.309 grams of benzene and 114.254 grams of
toluene. At a given temperature, pure benzene has a vapor pressure
of 38.50 torr, while pure toluene has a vapor pressure of 8.99

Benzene and toluene form nearly ideal solutions. The boiling
point of pure benzene is 80.1°C. Calculate the chemical potential
of benzene relative to that of pure benzene when xbenzene = 0.30 at
its boiling point. If the activity coefficient of benzene in this
solution were actually 0.93 rather than 1.00, what would be its
vapour pressure?
