Acetylsalicylic acid (C9H8O4) is a monoprotic acid commonly known as "aspirin." A typical aspirin tablet, however, contains only a small amount of the acid. In an experiment to determine its composition, an aspirin tablet was crushed and dissolved in water. It took 12.25 ml of 0.1466 M NAOH to neutralize the solution. Calculate the number of grains of aspirin in the tablet. (One grain = 0.0648 g.) Reaction is shown below. * COOH COONA + NaOH + H,O OCOCH OCOCH3 ASPIRIN O 4 7
