Calculate the activity and the rational activity coefficient of the water in a solution consisting of 122 g of a non-volatile solute (molar mass = 241 g mol-1) dissoved in 0.920 kg of water at 20°C. At 20°C the vapor pressure of pure water is 2339 Pa, and the partial pressure of the water above the solution is 2269 Pa.

Answer from back of textbook: aH2O=0.970; fH2O=0.980
