You take 1.00 g of an aspirin tablet (a compound consistingsolely of carbon, hydrogen, and oxygen), burn itin air, and collect 2.20 g CO 2 and 0.400 g H 2 O . Youknow that the molar mass of aspirin is between 170 and190 g/mol. Reacting 1 mole of salicylic acid with 1 moleof acetic anhydride (C 4 H 6 O 3 ) gives you 1 mole of aspirinand 1 mole of acetic acid (C 2 H 4 O 2 ) . Use this informationto determine the molecular formula of salicylic acid.
