How much CO₂ is produced by a car driven 20 * 10⁴ mi in one year? Assume the following:
• A car gets 20.0 mi/4.0 L of gasoline.
• Gasoline has the chemical formula of octane: C₈H₁₈.
• One liter of gasoline has a mass of 0.80 kg.
• Gasoline is completely burned to carbon dioxide and water.

Question

Quizplus · Accepted Answer

Given the car's fuel efficiency and the distance driven, we can calculate the amount of CO2 produced. The complete combustion of octane (C8H18) produces CO2 and H2O. For every mole of octane burned, 8 moles of CO2 are produced. Given the mass of gasoline used and its density, we can find the total mass of CO2 produced. The correct calculation leads to the answer in option B, which accounts for the stoichiometry of the combustion reaction and the given data.
