Calculate the number of pounds of CO 2 released into theatmosphere when a 21.0 gallon tank of gasoline is burned in anautomobile engine. Assume that gasoline is primarily octane, C 8 H18 , and that the density of gasoline is 0.692 g ⋅ mL − 1 . Thisassumption ignores additives. Also, assume complete combustion.Useful conversion factors: 1 gallon = 3.785 L 1 kg = 2.204 lb
