1. Caffeine has a distrubution coefficient of 8.4 for methylene chloride/ water. How much caffiene will be extracted from a 200 mL cup of Turkish coffee (250 mg caffeiene) by 100 mL of methylene chloride?
answer x= 0.202 mg
2. How many mg of caffeine would be extracted if an identical cup of coffee (as in question 1) were extracted with 2 successive 50 mL aliquots of methylene chloride? Which technique is more efficient?
