2. (4 points) How many grams of caffeine, Caff, would be extracted out of an aqueous solution containing \( 10.00 \mathrm{~g} \mathrm{Caff} / 100 \mathrm{~mL} \mathrm{H} 2 \mathrm{O} \) by washing the solution with \( 2 \times 50 \mathrm{~mL} \) batches of fresh chloroform, \( \mathrm{CHCl}_{3} \), given the following distribution coefficient: \[ \mathrm{K}=\frac{[\text { Caff }]_{\mathrm{CHCl} 3}}{\left[\text { Caff] }_{\mathrm{H} 2 \mathrm{O}}\right.}=1.5 \] Give your answer to two decimal places. 3. (3 points) Your not-too-bright lab partner adds so much \( \mathrm{MgSO}_{4} \) to a solution of caffeine in diethyl ether that no liquid can be seen anymore. In 1-4 sentences describe how you can recover the caffeine you have worked so hard to isolate.
