    Answer:

    91.224 mg of caffeine will be extracted from a 60 mL cup of Turkish coffee (100 mg caffeine) by 40 mL of methylene chloride (CH2Cl2)

    Explanation:

    The distribution co-efficient of Caffeine for methylene chloride (CH2Cl2)/water (H2O) is   8.4

    Volume of Turkish coffee = 60 mL

    Volume of methylene chloride (CH2Cl2) = 40 ml

    Distribution coefficient is represented by K

    8.4 = \frac{\frac{X}{60}}{\frac{100-X}{50} } \\X = 91.224 mg
