    The metal is not gold.

    Explanation:

    It is known that the density of gold (d) = 19.32 g/mL.

    We need to calculate the density of the given data of the metal and compare with the theoretical density value:

    Density (d) = mass/volume

    ∴ d of metal = mass/volume = (8.7 g) / (3.2 mL) = 2.72 g/mL.

    So, the metal is not gold.
