Submitted together due to required continuity between question parts.

If 2.0 grams of salicylic acid, 5.0 mL of acetic anhydride (density= 1.08 g/mL) and 5 drops of concentrated phosphoric acid are used in the reaction making aspirin, what is the limiting reactant? Select one: a. salicylic acid acetic anhydride phosphoric acid For the question above, what would be the theoretical yield of aspirin? Select one: 9.6 g 2.6 g 2.0 7.4 g If 1.8 g of aspirin were obtained in this experiment, what would be the percentage yield? Select one: 69% 0.69 % 19% 24.3% If 0.100 grams of your product was dissolved in a 50 mL solution of iron (III) nitrate and the absorbance of the solution at 525 nm was 0.500. what is the percent salicylic acid (by mass) in your product? Assume that the extinction coefficient for the complex is 950 M^-1 cm^-1 and the pathlength is 1 cm. Select one: 3.6% 1.1% 9.4% 4.7%
