Automobiles are often implicated as contributors to global warming because they are a source of the greenhouse gas CO2.
How many pounds of CO2 would your car release in a year, if it was driven 150. miles per week?
In your calculations, assume that gasoline is octane (molecular formula C8H18)
and that its burned completely to CO2 and H2O in the engine of your car.
Also assume that the car averages 25.3 miles per gallon and the density of octane is 0.703 g cm-3.
