1) Calculate the theoretical yield of aspirin obtained when 2.0 g of salicylic acid and 5.0 mL of acetic anhydride (density = 1.08 g/mL) are mixed together. (Molar masses: acetic anhydride = 102.1 g/mol; salicylic acid = 138.2 g/mol)
2) If 1.6 g of aspirin were obtained in this experiment, what would be the percentage yield?
3) The melting point of the crude aspirin was reported as 126 °C. What does it indicate about the purity of the product?
