A sample of water contaminated with pesticide is extracted with methylene chloride for determination of the pesticide. In experiments with a standard solution, it is found that when a 100 mL water sample is extracted with 30 mL of methylene chloride, 75% of the pesticide is removed. What fraction of the pesticide would be removed if three extractions of 10 mL of methylene chloride each were done instead?
