Question

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 −157

°

.

If this

solution were mixed with

500 mL

of a solution containing

5 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?
