![The complete combustion of octane, C₈H₁₈, a component of gasoline, proceeds as follows:
\[ 2\text{C}_8\text{H}_{18}(l) + 25\text{O}_2(g) \rightarrow 16\text{CO}_2(g) + 18\text{H}_2\text{O}(g) \]
**Relevant Volumetric Equivalencies:**
- 1 gallon (gal) = 3.785 liters (L)
- 1 liter (L) = 1000 milliliters (mL)](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F18451349-f722-4343-9ced-dbc580baaa92%2F60c8e2fa-2815-4228-aa04-9384a80b0c7f%2Fba973c_processed.png&w=3840&q=75)
