A student performed this extraction experiment, and he started with 0.070 g of caffeine dissolved in 4.0 mL of water. The caffeine was extracted from the aqueous solution by a series of two extractions. In the first extraction, 2.0 mL of methylene chloride was used and in the second extraction, 3.0 mL of methylene chloride was used. Calculate the total amount of caffeine that was extracted after this series of extractions. Caffeine has a distribution coefficient of 4.6, between methylene chloride and water. Show your calculations below. Use appropriate statements in each step.
