The partition coefficient for caffeine between dichloromethane and water is 4.6. assume that your 100 ml tea solution (in water) contained 0.10 g of caffeine. what is your theoretical yield of caffeine if: you extract with only one 15 ml portion of ch2cl2?

Theoretical yield is 0,041g of caffeine

Explanation:

The partition coefficient formula is:

Where k is partition coefficient (4,6)

The Caffeine in water at equilibrium will have a concentration of:

(0,10g-x) / 100mL

And Caffeine in dichloromethane will be:

xg / 15mL -Where x grams are the theoretical yield of caffeine-

Replacing:

6,9 - 69X = 100X

6,9 = 169X

0,041 g = X

I hope it helps!
