10. Calculate the theoretical yield of aspirin using 4.00 g of salicylic acid as the starting material. Assume acetic anhydride is in excess. (Hint: from the mass of salicylic acid acid use, how many moles of salycilic acid are present intitially? What is the salycilic acid : acetylsalicylic acid molar ratio? How many moles of acetylsalicylic acid are formed assuming 100% yield? Based on this abount of moles, how many grams of acetylsalicylic acid are formed? (this is the theoretical...
calculate the theoretical yield of acetylsalicylic acid if 2.50g salicylic acid is allowed to react with 2.00g of acetyl chloride in excess pyridine.
14.0 g of acetylsalicylic acid were obtained from 23.9 g of salicylic acid. Determine the percentage yield of acetylsalicylic acid. What I did: 23.9 g ÷ 138 g = 0.1732 mol Known Information: Reactant mass: 23.9 g Product mass: 14.0 g Reactant moles: 0.1732 moles *Please help: How would I solve for the Theoretical maximum moles of acetylsalicylic acid? acetylsalicylic acid C₉H₈O₄ (12•9) + (1•8) + (4•16) = 180 g/mol Would it be 14.0 g ÷ 180 g? Please explain.

In this lab you are synthesizing acetylsalicylic acid (ASA) from salicylic acid using acetic anhydride, with phosphoric acid as a catalyst. If the amount of salicylic acid at the start of the reaction was 1.05 g, what is the theoretical yield of ASA in g? Assume acetic anhydride is in excess.
A chemist synthesized 0.15 g of acetylsalicylic acid by reacting 0.200 g of salicylic acid with 0.450 mL acetic anhydride. Determine the theoretical yield and percent yield and percent recovery
Please help me solve this and show the full calculations. Calculate the limiting reactant, theoretical yield, and percent yield using the following: 2.0 g of salicylic acid and 5 mL of acetic anhydride, along with 10 drops of phosphoric acid, were used to make acetylsalicylic acid. This is a 1:1 mole ratio.
