7. [20 points] Ten grams of benzene was released into a closed environmental chamber containing 1.0 m2 of air, 0.1 m3 of water and 0.01 m3 of octanol present as a separate liquid phase. The chamber has a fixed temperature of 20C or 293 K. Determine the mass of benzene present in each of the three phases at equilibrium. The octanol-water partition coefficient for benzene is 130, the vapor pressure for benzene is 12.7 kPa, and the Henry's Law Constant for benzene is 0.55 kPa-m3/mol
