Assuming that it undergoes complete combustion, all of the
carbons from methane would be converted to carbon dioxide. Thus you would be
able to know the % yield of product by converting everything first to moles
then dividing the product with the reactant. The moles of methane is 0.023375
while the moles of carbon dioxide is 0.02234. In calculating for the % yield
divide the moles of CO2 with moles of methane and you would get 95.58%.
