Write the balanced equation for the combustion of isooctane (C₈H₁₈) to produce carbon dioxide and water. Use the smallest possible integers to balance the equation. Also, separate the + sign with 1 space and enter the reaction arrow as hyphen + greater than sign: ->

2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O

Assuming gasoline is 89.0% isooctane, with a density of 0.692 g/mL, what is the theoretical yield (in grams) of CO₂ produced by the combustion of 1.69 x 10¹⁰ gallons of gasoline (the estimated annual consumption of gasoline in the U.S.)? Remember, there are 3.785 liters in 1 gallon and assume that isooctane is the only carbon containing component of gasoline.
