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!

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.
