Viktor measures out 2.100 g of the ibuprofen from the bottle and dissolves it in 15.0 mL of ethanol. He transfers this solution to a 1.0 dm long tube and the polarimeter gives him a reading of +7.3416 deg for this sample. The literature specific rotation for ibuprofen is 57 deg. What is the observed specific rotation for this sample? What is the enantiomeric excess (EE) for this sample?
