Mole-mole problem: One disadvantage of burning propane (C3H8) is that carbon dioxide is one of the products. The released CO2 increases the
growing concentration of CO2 in the atmosphere. How many moles of carbon dioxide are produced when 10.0 moles of
propane are burned in excess oxygen on a gas grill? C3H8 + 502 → 3C02 + 4H20
