A website promoting the use of alternative energy vehicles and hybrid technologies claims that "A typical automobile in the USA uses about 500 gal of gasoline every year, producing about 5 tons of carbon dioxide." To determine the truth of this statement, calculate how many tons of carbon dioxide are produced when 500.0 gal of gasoline are combusted. Assume that the primary ingredient in gasoline is octane, C H₁ (1), which has a density of 0.703 g · mL-¹. 18 CO₂ produced: tons
