A sample of 0.8281 g of phenylsuccinic acid was dissolved in 10 mL of acetone. This sample gave a reading, aobs, of +10.278 deg on the polarimeter. A tube measuring 1 dm was used for the sample. Calculate the enantiomeric excess (EE) of the sample. The literature-specific rotation, [a]lit, of phenylsuccinic acid in acetone is 173 deg. Give your answer to 3 significant figures. Calculate the percent (%) of (+)-phenylsuccinic acid that is in this sample. Give your answer to 3 significant figures. Calculate the percent (%) of (-)-phenylsuccinic acid that is in this sample. Give your answer to 3 significant figures.
