Commercial ibuprofen tablets contain 200 mg of ibuprofen each. The commercial tablets have the active ingredient (ibuprofen) in addition to several other additives (e.g. starch, sucrose, etc) to assist in digestion. There are 6 tablets that are used in the experiment. The maximum amount of available ibuprofen is (6 x 200 mg) = 1200 mg. Crude ibup. Pure Ibup (after recrys.) Six pills m.p. Gross mass (g) 2.89 29.50 2.09 Tare mass (g) 0.89 28.32 1.00 Net mass (g) 2 g 1.18 g 1.09 g 70-71C 1) Calculate the percentage of ibuprofen in each pill. 2) Calculate the percent recovery of ibuprofen from the pills, based on the crude ibuprofen mass. 3) Calculate the percent recovery of pure ibuprofen from the crude.
