4. Propane, C3H8, can be used as a fuel in your home, car, or grill because it is easily liquefied and
transported. If 454 g of propane is burned, what mass (in grams) of oxygen, O2, is required for
complete combustion? HINT: look back at your notes on combustion reactions if you cannot
remember what the reactants and products are.
C3H8 + –––> +
