A large bucket somehow gets contaminated with some gardening pesticide and was then filled with 2 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 1.0% by weight. You have a single container of 1.8 L'of MTBE that has a Kd = 20 for this pesticide and you plan to do 3 extractions. While pouring the MTBE for the first extraction, you spill 325 mL on the ground, with only 375 mL mixing with the water. That leaves only 1.1 L to split for the 2nd and 3rd extractions. What will be the final concentration (in weight %) of the pesticide remaining in the water?

A large bucket somehow gets contaminated with some gardening pesticide and
was then filled with 2 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 1.0% by weight. You have a single container of 1.8 L'of MTBE that has a Kd =
20 for this pesticide and you plan to do 3 extractions. While pouring the MTBE
for the first extraction, you spill 325 mL on the ground, with only 375 mL mixing
with the water. That leaves only 1.1 L to split for the 2nd and 3rd extractions.
What will be the final concentration (in weight %) of the pesticide remaining in
the water?
