A chemist wants to extract a solute from 100 mL of water using only 300 mL of ether. The distribution constant, D , between ether and water is 2.96. Calculate , the fraction of solute that would remain in the water under each of the extraction conditions.

1)The chemist performs a single extraction with 300 mL of ether.

=

2)The chemist performs three extractions with 100 mL of ether.

=

3)The chemist performs six extractions with 50 mL of ether.
