(4 points) ii) Although each beaker contains only aqueous tartaric acid, beaker 'X' contains solute molecules of only o n e molecular structure; beaker 'Y' contains solute molecules of t w o molecular structures; and beaker 'Z' contains solute molecules with t h r e e distinct molecular structures. Indicate (using structures or unambiguous names) the molecular species in solution in each beaker. (6 points) b) If you took 10.0 mL of a solution containing 1 gram of L-tartaric acid, and placed it in a 2 dm tube, what value would you observe for a, the optical rotation? (3 points)...
