(Answered) A system consisted of 50 mg of an organic compound

Academics

A system consisted of 50 mg of an organic compound dissolved in 1.00 mL of water (solvent A). Compare the effectiveness of one 2.00 mL extraction versus two 1.00 mL extractions with ether (solvent B) where the distribution coefficient, K, is equal to 2. The answer gives you a fraction of the amount of organic compound extracted into solvent B, ether. How much material (in mg) is left in the water layer? Discuss which extraction method is preferable; one or two extractions?
