    7.0 g/mL.

    Explanation:

    Density is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and the volume it takes up.

    d = m/V,

    where, d is the density of the metal,

    m is the mass of the metal (m = 147 g),

    V is the volume that the metal takes up (V = 41.0 mL - 20.0 mL = 21.0 mL).

    ∴ d = m/V = (147 g) / (21.0 mL) = 7.0 g/mL.
