2) The distribution coefficient between methylene chloride and water for solute Y is 9. An amount of 107.0 g of Y is dissolved in 150 mL of water.
a) What weight of Y would be removed from water with a single extraction with 150-mL of methylene chloride? Report to 1 decimal place.
b) What weight of Y would be removed from water (the original solution) with twosuccessive extractions with 75-mLportions each of methylene chloride? Report to 1 decimal place.
3) You have 141.0 g of solute Q dissolved in 140-mL of water. The distribution coefficient between ether and water for solute Q is 7. What volume of ether would you need to extract 98.0 g of solute Q in oneextraction from the original 141.0g dissolved in 140 mL water? Provide answer to closest mL. (Show calculations)
