    Answer:

    345.44 g or 0.34544 kg

    Explanation:

    Applying

    D = m/V…………………. Equation 1

    Where D = Density of mercury, m = mass of mercury, V = Volume of mercury.

    make m the subject of the equation

    m = D×V…………….. Equation 2

    From the question,

    Given: D = 13.6 g/mL = 13.6 g/cm³, V = 25.4 cm³

    Substitute these values into equation 2

    m = 13.6×25.4

    m = 345.44 g

    m = 0.34544 kg

    Hence the mass of mercury is 345.44 g or 0.34544 kg
