Write balanced chemical equation and determine the molecular weight of the reactants.

1.Within the cylinders of a car's engine, the hydrocarbon octane (C₈H₁₈), one of the many components of gasoline, mixes with oxygen from the air and burns to from carbon dioxide and water vapor. Write a balanced equation for this reaction.

2.Aspirin (acetylsalicylic acid, C₉H₈O₄) can be made by reacting salicylic acid (C₇H₆O₃) with acetic anhydride [(CH₃CO)₂O] by the following reaction:

C₇H₆O_{3 (}s₎ + (CH₃CO)₂O₍l₎ à C₉H₈O_{4 (}s₎ + CH₃COOH₍l₎

Calculate the molecular weights of the reactant(s).

3. If you take 4-500mg tablets of aspirin, how many molecules of aspirin did you ingest?
