A mixture of CH4 (g) and C2H6 (g) has a total pressure of 0.53 atm. Just enough O2 was added to the mixture to bring about it's complete combustion to CO2 (g) and H2O (g). The total pressure of the two product gases is found to be 2.2 atm. Assuming constant volume and temperature, find the mole fraction of CH4 in the original mixture.
