Aspirin is the analgesic acetylsalicylic acid C9H8O4. What is the coefficient of aspirin in the balanced equation for the combustion of solid acetylsalicylic acid to carbon dioxide and liquid water?

1

Explanation:

C9H8O4 + 9 O2 = 9 CO2 + 4 H2O.

The coefficent is 1

The answer to your question is C₉H₈O₄ + 9O₂ ⇒ 9CO₂ + 4H₂O
