Question:

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 xbmzenc = 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?
