An aqueous solution containing 10 g of an optically pure compound was diluted to 500 mL with water and was found to have a specific rotation of −121º. If this solution were mixed with 500 mL of a solution containing 3 g of a racemic mixture of the compound, what would the specific rotation of the resulting mixture of the compound? What would be its optical purity?

An enantiopure naturally occurring sugar had a specific rotation of +136. A synthetic sample of this sugar gave a rotation of +84°, when a sample of concentration 1.37 g/100 ml was placed in a cell with a path length of 20 cm. (i) Which of the following prefixes could be used to describe this compound (on the basis of the information provided) +/-, d/l, D/L, R/S? (ii) Calculate the ee of the synthetic sample.

CH, CH, Q3: The specific rotation of L-alanine in water (at 25°C) is +2.8. A chemist prepared a mixture of L-alanine and its enantiomer, and 3.50 g of the mixture was dissolved in 10.0 mL of water. This solution was then placed in a sample cell with a pathlength of 10.0 cm and the observed rotation was +0.78. Calculate the % ee of the mixture.
