100 mL of aqueous solution containing 2,4,6-trinitrotoluene (TNT) at an initial concentration of 0.05 ppm is shaken with 10 mL hexane. After the phase separation, it was determined that the organic phase has 0.4 ppm. What is the partition coefficient, and what is the percent extracted? If the equilibrium concentration (rather than initial concentration) is 0.05 ppm, this would simplify the calculation. What would then be the partition coefficient and percent extracted? (Please answer or provide something for the second...

In this experiment, 0.070 g of caffeine is dissolved in 4.0 ml of water. The caffeine is extracted for the aqueous solution 3 times with 2.0 ml portions of methylene chloride. The methylene chloride extracts are combined and the solvent evaporated resulting in isolated caffeine crystals. Briefly explain why caffeine will prefer the methylene chloride solvent to the water solvent. You need to draw the structures for all three compounds.
