A sample of propane (c3h8) is placed in a closed vessel together with an amount of O2 that is 2.50 times the amount needed to completely oxidize the propane to CO2 and h20 at constant temperature. Calculate the mole fraction of each component in the resulting mixture after oxidation assuming h20 is present as a gas.
