A website promoting the use of alternative energy vehicles and hybrid technologies claims that "A typical automobile in the USA uses about 40 gal of gasoline every month, producing about 750 lb of carbon dioxide." To determine the truth of this statement, calculate how many pounds of carbon dioxide are produced when 40.00 gal of gasoline are combusted. Assume that the primary ingredient in gasoline is octane, C8H18(l), which has a density of 0.703 g·mL−1.
