Calculate the theoretical yield of aspirin to be obtained in experiment, 2.0 grams of salicylic acid and 5.0 mL of acetic anhydride (density = 1.08g/mL). Molecular mass salicylic acid = 138.118 g/mol Molecular mass acetic anhydride = 102.09 g/mol ------------------------------------------------------------- I got 0.05289 moles of acetic anhydride 0.01448 moles of salicylic acid Balanced equation: C7H6O3 + C4H6O3 C9H8O4 + C2H4O2 mole ratio is one to one Limiting reaction is salicylic acid since it has less moles So for one mole of salicylic acid used one mole of aspirin is used too. So there are 0.01448 moles of aspirin? Molecular mass of aspirin = 180.157 g/mol (180.157 g/mol) (0.01448 mol) = 2.608g of aspirin Is this correct? Thank You. 2.608g is the theoretical yield of aspirin
