Aspirin (MM = 180.2) is prepared from the reaction of salicylic acid (MM = 138.1) and acetic anhydride (MM = 102.1). Assuming 100% yield, how many grams of aspirin can be synthesized if 20.0 g of salicylic acid and 20.0 g of acetic anhydride were initially used? COOH Dalsla + CH3-C-0-C- OH (C7H6O3) Salicyclic acid (s) COOH (C₂H60₂) Acetic anhydride () (CgH8O4) Aspirin (s) -CH3 OCCH3 0 + CH3COOH (C₂H₂O₂) Acetic acid ()
