In this experiment, 0.170g of caffeine is dissolved in 10.0mL of water. The caffeine is extracted from the aqueous solution three times with 5.0-mL portions of methylene chloride. Calculate the total amount of caffeine that can be extracted into three portions of methylene chloride. Caffeine has a distribution coefficient of 4.6 between methylene chloride and water.
