To calculate the theoretical yield of acetylsalicylic acid aspirin , we need to first determine the limiting reagent in the reaction. 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 find the moles of each reactant:Moles = mass g / molar mass g/mol The molar mass of salicylic acid C7H6O3 is 138.12 g/mol, and the molar mass of acetic anhydride C4H6O3 is 102.09 g/mol.Moles of salicylic acid = 5 g / 138.12 g/mol = 0.0362 molMoles of acetic anhydride = 10 g / 102.09 g/mol = 0.0979 molNow, we need to determine the limiting reagent by comparing the mole ratio of the reactants:Mole ratio = moles of salicylic acid / moles of acetic anhydride = 0.0362 mol / 0.0979 mol = 0.369Since the mole ratio is less than 1, salicylic acid is the limiting reagent.Now, we can calculate the theoretical yield of aspirin C9H8O4 using the stoichiometry of the balanced equation:Moles of aspirin = moles of salicylic acid = 0.0362 molThe molar mass of aspirin is 180.16 g/mol.Mass of aspirin = moles of aspirin molar mass of aspirin = 0.0362 mol 180.16 g/mol = 6.52 gTherefore, the theoretical yield of acetylsalicylic acid aspirin that can be obtained from 5 grams of salicylic acid and 10 grams of acetic anhydride is 6.52 grams, assuming a 100% conversion rate and perfect reaction conditions.
