You are given a steel vessel containing a mixture of methane gas (CH4 (g)) and propane gas (C3H8 (g)). You completely combust this entire mixture in the presence of excess oxygen gas, and you collect all of the carbon dioxide and water formed in the combustion reaction. A total of 48.4 grams of CO2 and 32.4 grams of H2O are collected. Determine the number of moles of CH4 (g) and C3H8 (g) that were present in the initial mixture.
