Question

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.

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.
4) Why does the melting point (70-71)above match neither the enantiomers' nor the
racemate's? Does it mean that the substance is impure, or perhaps isn't even ibuprofen
at all? (Racemic mixture:75-77C, Enantiomer:52-53C)
