It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn't come from the gasoline itself, but the oxygen in the air. When gasoline burns, the carbon and hydrogen separate.
A carbon atom has a weight of 12, and each oxygen atom has a weight of 16, giving each single molecule of CO 2 an atomic weight of 44 (12 from carbon and 32 from oxygen). Therefore, to calculate the amount of CO 2 produced from a gallon of gasoline, the weight of the carbon in the gasoline is multiplied by 44/12 or 3.7.
