Expert Solution
Step 1: Provided information

Provided, 

0.0719 caffeine is dissolved in 4.00 mL of deionized water and extracted with mL of dichloromethane.

The partition coefficient for the extraction is 4.06.

You can use the partition coefficient (K) and the initial concentration of caffeine in water to determine the mass of caffeine extracted into dichloromethane. The partition coefficient represents the ratio of a solute's concentration in one phase to its concentration in another phase in equilibrium.You can use the partition coefficient (K) and the initial concentration of caffeine in water to determine the mass of caffeine extracted into dichloromethane.
