A 10-mg quantity of phenanthrene (MW = 178) is added to a 1-L flash containing 500 mL of air and 500 mL of water. Predict the aqueous phase equilibrium concentration of phenanthrene at 25*C if the values for this compound are Cs = 1.1 mg/L, P^v = 1.6 x 10^-7 atm, KH = 4.0 x 10^-5 atm*m^3/mol, and logKow = 4.52.
