A gaseous mixture consists of 80.0 mole percent N2 and 20.0 mole percent 02. Suppose water is saturated with the gas mixture at 25 c and 1 atm total pressure, and then the gas is expelled from the water by heating. What is the composition in mole fractions of the gas mixture that is expelled? The solubilities of N2 and O2 at 25 c and 1 atm are .0175 g/LH2O and .0393 g/LH2O, respectively.
