A large bucket somehow gets contaminated with some gardening pesticide and was then filled with 5 L of water. Rather than dumping the contaminated water into the environment, you decide to use your knowledge of liquid-liquid extractions to remove the pesticide from the water. The pesticide concentration is at 1% by weight. You have a six 1-Liter bottles of MTBE that has a Kd = 15 for this pesticide and you plan for 3 extractions. For the first extraction, you use up 3 bottles of MTBE. For the 2nd extraction, you use 2 more bottles. The final extraction uses the remainder of the solvent. What will be the final concentration (in weight %) of the pesticide remaining in the water?
