A 72.0 g sample of an organic solid is dissolved in 180mL of water. The solid is extracted using one 60 mL extraction in the first extraction of an organic solvent which has a partition (distribution) coefficient with water of 10. The first extraction removed 55.4 g of solid from water. What are the numbers that need to go in box A and B to calculate the volume of solvent (y) that would be necessary to remove an additional 7.0g from the remaining sample dissolved in water. You DON'T have to complete the calculation to solve for y.

2. Look up the solubility data for benzoic acid in the solvent toluene. Is benzoic acid more or less soluble in toluene than water? Why? 3. What would be a disadvantage of using toluene in this experiment? J 2. Look up the solubility data for benzoic acid in the solvent toluene. Is benzoic acid more or less soluble in toluene than water?

1a. Use the given table to construct a temperature-composition diagram for cyclohexane Toluene mixture. Based on the plot, what is the composition of the distillate obtained by Simple distillation 20 mole percent cyclohexene and 80 mole percent toluene? Show your  Work on the plot. 1b. Estimate the composition of the distillate of 20 mole percent of cyclohexane if the  Distillation column had three theoretical plates.

Consider 15 mL of an aqueous solution containing 2.0 g of an organic solute. If the distribution coefficient for the solute between ether and water is 20, calculate the percent of the compound that can be recovered with a single extraction with 13.3 mL of ether. to two significant figures.
