Calculate the theoretical yield of aspirin if 105 g of salic

Calculate the theoretical yield of aspirin if 1.05 g of salicylic acid is combined with

Solution

milimoles of salicyclic acid reacted =1.05/138.12 = 7.602

milimoles of acetic anhydride reacted = (1.08 * 2)/102.09 = 21.15 (excess)

hence,milimoles of aspirin formed =7.602

theoretical yield = (0.007602* 180.167) = 1.369 gm
