Calculate the mass (in pounds) of carbon dioxide and carbon monoxide emitted by burning a gallon of gasoline. Although gasoline is a mixture of many components, simplify the calculation assuming the gasoline fuel is 20% n-heptane, 40% n-octane, 20% n-nonane and 20% n-decane on a mass basis. You may also assume that gasoline behaves ideally, and 90% of each component of the fuel combusts conpletely, with the balance combusting inconpletely.
