Aspirin (C9H8O4) is Synthesized by reacting the salicylic acid, with acetic anhydride:
2C7H6O3(s) + C4H6O3(l) → 2C9H8O4(s)+ H2O(l)
Salicylic acid acetic anhydride aspirin calculate the mass of aspirin that can be organized by this reaction if 8.000 grams of salicylic acid are reacted with an surplus of acetic anhydride.
