A student synthesised 1.50 g aspirin (C3H04) in a laboratory by reacting 1.50 g salicylic acid (C,H,Os) with 2.00 g acetic anhydride (CHO). The balanced equation is CyH6O3 + C.H.O, CH,O4 + HC2H302 Molar masses (g/mol): CyH603 = 138.12; C.H:03 = 102.09; CH304 = 180.16 (a) Which compound is the limiting reactant? (b) What is the theoretical yield of aspirin? (c) How much of excess reactant in grams remains after the reaction is completed? (d) What is the percentage yield? (3) (2) (2) (2)
