An experiment was carried out to synthesize acetylsalicylic acid from salicylic acid. salicylic acid acetylsalicylic acid 12.7 9 of acetylsalicylic acid were obtained from 23.1g of salicylic acid. Determine the percentage yieid of acetylsalicylic acid. Determine the moles of salicylic acid, C7H6O3, used in the experiment. (To avoid introducing rounding errors on intermediate calculations, enter your answer to four significant figures.) Moles of salicylic acid used = mol
