Chapter 9, Problem 49E

Calculate the amount of carbon dioxide (in kg) emitted into the atmosphere by the complete combustion of a 15.0 gallon tank of gasoline. Do this by following these steps:

Assume that gasoline is composed of octane $\left({\text{C}}_{\text{8}}{\text{H}}_{\text{18}}\right)$. Write a balanced equation for the combustion of octane.

Determine the number of moles of octane contained in a 15.0 gallon tank of gasoline (1 gallon = 3.78 L). Octane has a density of 0.79 g/mL.

Use the balanced equation to convert from moles of octane to moles of carbon dioxide, then convert to grams of carbon dioxide, and Finally to kg of carbon dioxide.
