1. A student finds after thorough mixing that the concentrations of a solute in a water layer and in a gasoline layer were ( 0.16 mathrm{mg} / mathrm{mL} ) and ( 15 mathrm{mg} / mathrm{mL} ) respectively. Calculate the extraction coefficient ( mathrm{K}_{frac{ ext { Gasoline }}{mathrm{H}_{2} mathrm{O}}} ).

1. 36 mg of compound X was dissolved in water to form a 100.0 mL. The solution was mixed with ether. If the distribution coefficient K = 4, What is the volume of ether required to extract 24 mg of the compound X from the water solution? 2. An extraction of compound X proceeds with a distribution coefficient of 20. A mass of 5.0 g of organic compound X is dissolved in 100 mL of water. Calculate the mass of compound X remaining in the aqueous solution after an extracted using 50 mL portions of dichloromethane. 3. A compound X was dissolved in water to form a solution with a concentration of 360 ppm. 100.0 mL of the solution was mixed with 50.0 mL of ether. What is the distribution coefficient if 24 mg of the compound X was extracted by the organic solvent?
