To calculate the theoretical yield of aspirin, we first need to determine the limiting reactant in the reaction between salicylic acid and acetic anhydride. The balanced chemical equation for the synthesis of aspirin is:C7H6O3 salicylic acid + C4H6O3 acetic anhydride C9H8O4 aspirin + C2H4O2 acetic acid First, we need to convert the given amounts of reactants to moles. The molar mass of salicylic acid C7H6O3 is 138.12 g/mol and the density of acetic anhydride C4H6O3 is 1.08 g/mL, with a molar mass of 102.09 g/mol.Moles of salicylic acid = 2.0 g / 138.12 g/mol = 0.0145 molMoles of acetic anhydride = 5.0 mL * 1.08 g/mL / 102.09 g/mol = 0.0529 molNow, we need to determine the limiting reactant by comparing the mole ratio of the reactants:Mole ratio of salicylic acid to acetic anhydride = 0.0145 mol / 0.0529 mol = 0.274Since the stoichiometry of the reaction is 1:1, salicylic acid is the limiting reactant because the mole ratio is less than 1.Now, we can calculate the theoretical yield of aspirin using the stoichiometry of the reaction and the moles of the limiting reactant salicylic acid :Moles of aspirin = 0.0145 mol since the stoichiometry is 1:1 The molar mass of aspirin C9H8O4 is 180.16 g/mol, so we can convert moles of aspirin to grams:Theoretical yield of aspirin = 0.0145 mol * 180.16 g/mol = 2.61 gTherefore, the theoretical yield of aspirin that can be obtained from the reaction of 2.0 grams of salicylic acid and 5.0 mL of acetic anhydride is 2.61 grams.
