A mixture of methane gas, CH, (), and propane gas, C,H, (), has a pressure of 0.6205 bar when placed in a sealed container. The complete combustion of the mixture to carbon dioxide gas, Co, G), and water vapor, H,O(g), was achieved by adding exactly enough oxygen gas, O,(g), to the container. The pressure of the product mixture in the sealed container is 2.486 bar. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume remain constant.

Help me please
A mixture of methane gas, CH, (), and propane gas, C, H, (g), has a pressure of 0.620s bar when placed in a sealed
container. The complete combustion of the mixture to carbon dioxide gas, co,), and water vapor, H,O(g), was achieved
by adding exactly enough oxygen gas, O, (g), to the container. The pressure of the product mixture in the sealed container is
2.486 bar. Calculate the mole fraction of methane in the initial mixture assuming the temperature and volume
remain constant.
