Calculate the theoretical yield of aspirin to be obtained in this experiment, starting with 2.0 g of salicylic acid and 5.0 ml of acetic acid anhydride (density = 1.08 g/ml).
Writ the equation for salicylic acid + acetic anhydride to produce ASA.
This is a limiting reagent problem.
2a. Convert 2.0 g salicylic acid to mols.
2b. convert 5.0 mL to grams by density, then to mols.
3. Convert to mols ASA (aspirin)
a. Convert mols salicylic acid to mols ASA (1:1 ratio).
b. Convert mols acetic anhydride to mols ASA (1:1 ratio).
c. Choose the smaller number of mols ASA produced. The reagent producing this result is the limiting reagent.
4. Convert mols ASA in 2c to grams. That is the theoretical yield.
Post your work if you get stuck BUT tell me what you don't understand about the next step.
