    The answer to your question is letter C. 21900.3. My result was 21945 J, letter C is close to this result.

    Explanation:

    Data

    mass = 150 g

    temperature 1 = T1 = 10°C

    temperature 2 = T2 = 45°C

    Cw = 4.18 J/g°C

    Formula

    Q = mCΔT = mC (T2 - T1)

    Substitution

    Q = (150) (4.18) (45 - 10)

    Simplification

    Q = (150) (4.18) (35)

    Result

    Q = 21945 J
