The active ingredient in Aspirin™ tablets is acetylsalicylic acid, C₉H₈O₄₍s₎. Acetylsalicylic acid, commonly called ASA, is a monoprotic acid. To determine the percentage of ASA in a tablet, a student began by measuring the mass of one tablet. The mass was 0.370 g. The student then crushed the tablet and dissolved it in water. Finally, she titrated the solution with 0.0750 mol/L sodium hydroxide, NaOH(aq),using an indicator. The titration required 18.50 mL of0.0750 mol/L sodium hydroxide to reach the end point. What percentage of ASA was in the tablet?
