Question

Approximately 2.5 kg of carbon dioxide gas are produced for every liter of gasoline burned in an automobile gasoline engine. Calculate the number of pounds of carbon dioxide produced weekly by a driver who averages 125 miles per week in a car that gets about 35 mpg.

Answer 1

125 mile *1gallon/35 mi = 135/35 = (27/7) gallon gasoline 

27/7 gallon * 1 L/0.264 gallon = 14.6 L  gasoline

14.6 L gasoline * 2.5kg CO2/1L gasoline= 36.5 kg CO2

36.5 kg CO2 * 1lb/0.454 kg = 80.4 lb

Answer: 80.4 lb CO2
