In lab, you add 2.074 g salicylic acid to a 125 mL Erlenmeyer flask, as listed in the procedure. You carefully add 4.0 mL acetic anhydride and have your TA add 5 drops of sulfuric acid. After completing the synthesis and filtering, you place the crystals to dry on an evaporating dish that weights 21.682 g. After drying, the crystals and evaporating dish weigh 23.034. Calculate the percent yield of aspirin.
