We have a suspension of pure liquid o-xylene (mg 106 g mol"1), with a liquid vapor pressure of 8.7 x 103 atm, and an activity coefficient in water of 3.37 x 10*. starting with the fugacity equality f f where e is the pure xylene phase, derive and solve for an expression for the solubility (mg l) of o-xylene in water.
