A mixture of methane gas, CH4(g), and pentane gas, C5H12(g), has a pressure of 0.5015 atm when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, CO2(g), and water vapor, H2O(g), was achieved by adding exactly enough oxygen gas, O2(g), to the container. The pressure of the product mixture in the sealed container is 2.421 atm. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant. Xch4=
