8. Polarimetry data a. A student took 0.375 g of the product, (S)-phenylsuccinic acid, and dissolved it in 9.8 mL of acetone. This solution was placed in the observation tube and then the observed rotation was determined. The observed rotation, lobs, was 5.433 i. Given the observed rotation and the pathlength of the polarimeter cell (1 dm), calculate the specific rotation, (a). (1 point) ii. With your answer from 8i, calculate the enantiomeric excess, %ee. Optically pure (5)-(+)-phenylsuccinic acid is (alb= + 171°in acetone. (1 point) iii. With your answer from 8ii, how much of the recovered 0.275 g (from Q7b) is (5)-phenysuccinic acid and how much is (R)-phenylsuccinic acid? All answers should be reported in grams. (2 points)
