The following data was collected for this experiment: 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. What is the major enantiomer present in this sample? Calculate the concentration of the sample used in g/mL. Calculate the observed specific rotation [a]obs of the sample. Give your answer to 4 significant figures.
