1. Write the equation and balance it.
Convert 1 gallon octane to mL, then use the density to convert to grams.
Convert grams octane to mols octane (mols octane = grams/molar mass).
Using the coefficients in the balanced equation, convert mols octane to mols CO2.
Convert mols CO2 to grams CO2 by using grams CO2 = mols CO2 x molar mass CO2.
Convert g CO2 to pounds CO2.
Check my thinking. Post your work if you get stuck.
