C23-9 Solute S has a distribution constant of 3.7 between water (phase 1) and hexane (phase 2).Calculate the concentration of solute S in hexane if [S]water is 0.016 M.%3DJhexaneIf the volume of water is 65.0 mL and the volume of hexane is 17.0 mL, find the ratio of the moles of solute S in hexane to themoles of solute S in water.mol Shexanemol Swater

According to the mole concept, in terms of mass, the amount of substance in moles is equal to the ratio of its mass to the molar mass. The concentration in terms of molarity is defined as the ratio of the amount of moles of the solute per liter of the solution.We can calculate the concentration of hexane as follows: Partition coefficient=ShexaneSwater Shexane=Partition coefficient×Swater =3.7×0.016 M =0.0592 M Thus, the concentration of hexane is 0.0592 M. The number of moles of hexane is calculated as follows: nhexane=17.0 mL×1 L1000 mL×0.0592 M =1.0064 mol The number of moles of water is calculated as follows: nwater=65.0 mL×1 L1000 mL×0.016 M =1.04 mol Therefore, the ratio of moles of hexane to the moles of water is: mol Shexanemol Swater=1.0064 mol1.04 mol =0.967 Thus, the required ratio of the number of moles of hexane to water is 0.967.
