A natural gas mixture consists of 90 mole percent CH4 and 10 mole percent C2H6. Suppose water is saturated with the gas mixture at 20 degrees celcius and 1 atm total pressure, and the gas is the expelled from the water by heating. What is the composition in mole fractions of the gas mixture that is expelled? The solubilities of CH4 and C2H6 at 20 degrees celcius and 1 atm are .0175 g/L H20 and .059g/L H2O, respectively.
