1. The problem statement, all variables and given/known data When 100 mL of an aqueous solution containing 1.0 g of caffeine is extracted with 10 mL of chloroform at room temperature, 0.5 g of caffeine is transferred to the chloroform layer. Calculate the distribution coefficient of caffeine between chloroform and water at room temperature. 2. Relevant equations The only thing I have is that Kd=concentration of A in S/ concentration of A in S' where A= the solute and S/S' are the immiscible solvents 3. The attempt at a solution I have not a clue how to do this! If someone could walk me through it that would be great! thanks so much!
