Aspirin can be prepared from salicylic acid ( c 7 h 6 o 3 ), which has a molar mass of 138.12 g/mol, and acetic anhydride ( c 4 h 6 o 3 ), which has a molar mass of 102.04 g/mol. the density of acetic anhydride is 1.082 g/ml. c 7 h 6 o 3 + c 4 h 6 o 3 ⟶ c 9 h 8 o 4 + c 2 h 3 o 2 what is the yield of aspirin ( c 9 h 8 o 4 ), which has a molar mass of 180.15 g/mol, possible when reacting 2.18 g of salicylic acid with 1.01 ml of acetic anhydride?
