11. For each of the following questions, assume that all measurements are made in 10-cm polarimeter sample containers. (a) A 10-mL solution of 0.4 g of optically active 2-butanol in water displays an optical rotation of 20.568. What is its specific rotation? (b) The specific rotation of sucrose (common sugar) is 166.4. What would be the observed optical rotation of such a solution containing 3 g of sucrose? (c) A solution of pure (S)-2-bromobutane in ethanol is found to have an observed a 5 57.38. If [a] for (S)-2-bromobutane is 23.1, what is the concentration of the solution?
