Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Aspirin can be made in the laboratory by reacting acetic anhydride (C4H6O3C4H6O3) with salicylic acid (C7H6O3C7H6O3) to form aspirin (C9H8O4C9H8O4) and acetic acid (C2H4O2C2H4O2). The balanced equation isC4H6O3+C7H6O3→C9H8O4+C2H4O2C4H6O3+C7H6O3→C9H8O4+C2H4O2In a laboratory synthesis, a student begins with 3.10 mLmL of acetic anhydride (density=1.08gml−1density=1.08gml−1) and 1.23 gg of salicylic acid. Once the reaction is complete, the student collects 1.22 gg of aspirin. Determine the percent yield of aspirin for the reaction. Express your answer using three significant figures.
