How many grams of salicylic acid, C7 H6 O3 , are needed to make one aspirin tablet, which contains 0.33 g of aspirin?

Answer 1

Aspirin C9H8O4 is made when salicylic acid C7H6O3 reacts with ethanoic anhydride C4H6O3 . The equation for this reaction is: C7H6O3 + C4H6O3 → C9H8O4 + CH3COOH Calculate the maximum mass of aspirin that could be made from 100 g of salicylic acid
