You have 162.0 g of solute Q dissolved in 150-mL of water. The distribution coefficient between ether and water for solute Q is 5. What volume of ether would you need to extract 150 g of solute Q in one extraction from the original 162 g dissolved in 150 mL water? Provide answer to closest mL. (Show calculations)

QUESTION 9 (4b-301-196-3.69) A 196 gram sample of glucose (C6H1206) was used to make a 3.69 M solution. What is the volume of that solution? Show all work and give your answer with three sig figs. Note M(C6H1206) = 180.16 g/mol. QUESTION 10 (4b-401-1.53-1) An intern working in a research lab knocks over a beaker containing an important solution. The beaker originally contained 1.50 L of a 1.53 M solution, but after it spilled it only contained 1 L of solution. The intern decides to hide his mistake by refilling the beaker to contain 1.50 L again by adding pure water (not realizing that this will dilute the solution). What is the new concentration of the solution? Show all work and give your answer with three sig figs. Click Save and Submit to save and submit. Click Save All Answers to save all answers.
