You have 75.0 g of solute Q dissolved in 300-mL of water. The distribution coefficient between ether and water for solute Q is 8.
a) How many extractions using 60-mL of ether each would you need to carry out to extract a total of 70.7 g (total) solute Q from water?
b) What volume of ether would you need to extract 70.7 g of solute Q in one extraction from the original 75.0g dissolved in 300 mL water? Provide answer to closest mL.
