Aspirin is produced in a student lab. One mole of salicylic acid (MM 138 g/mole) reacts with one mole of acetic anhydride (MM 102 g/mole), producing one mole of aspirin (MM 180 g/mole) and one mole of acetic acid, commonly known as vinegar (MM 60 g/mole). The student reacts 2.054 g of salicylic acid with 5.00 mL (density 1.00 g/mL) of acetic anhydride. After heating, crystallizing, and filtering, the collected product weighed 2.189 g.
