You will be using 1.4 grams of salicylic acid to make aspirin. Salicylic acid is the limiting reagent and one mole of salicylic acid makes one mole of aspirin. Calculate the theoretical yield of aspirin from this week's experiment (i.e. calculate the grams of aspirin produced from 1.4 gram salicylic acid).
