When octane (C₈H₁₈, density = 0.699 g/mL) undergoes complete combustion, it provides energy according to the reaction: 2C₈H₁₈ (l) + 25O₂ (g) → 16CO₂ (g) + 18H₂O (l) ΔH° = −10,932 kJ How much heat, in kJ, is produced by the amount of octane needed to drive 571 kilometers in a car that averages 12.7 km/L?
