Academics

Home many Mg of caffeine will be obtained by extracting 300 ml of water solution containing 420 Mg of caffeine with two successive 30 ml portions of methylene chloride . Assume that the partition coefficient is 9.0 . How many Mg of catfish would be obtained if the same aqueous solution is extracted once with 60 ml of methylene chloride? Come pare the two results . In both experiments we use the same amount of organic solvent. However do we isolate the same amount of product in both experiment?
