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 −117°. 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?

Assume that optically pure (S)-2-iodononane has a specific rotation of + 9.5o (clockwise rotation of the plane-polarized light). Claculate the percentage of (S) enantiomer required when the specific rotation for a mixture of 2-iodononane enantiomers will be -2.1o (counterclockwise rotation of the plane-polarized light).
