Please answer all correctly. I will leave an upvote. Thank you for the help. $1.$ The solubility of caffeine in water is $1$g$/46$ml$.$ In dichloromethane, on the other hand, $1$ g can be dissolved

caffeine in $5$ ml$.$

a$)$ Calculate the partition coefficient for caffeine in water$/$dichloromethane$.$

b$)$ How much caffeine will be extracted from $250$ ml of water containing $500$ mg of caffeine

with one portion of dichloromethane of $100$ ml$?$

c$)$ How much caffeine would have been extracted if two $50$ ml portions of dichloromethane had

been used under point b$)?$

d$)$ The solubility of caffeine in diethyl ether is $1$g$/530$ ml$.$ How much caffeine can be extracted from $1$

liters of saturated solution of caffeine in water by a single extraction with $500$ ml of diethyl ether?
