    Answer:

    The density of copper is 8.9 grams per cubic centimeter.

    Explanation:

    There is a writing mistake in statement, correct form is written below:

    A 124.6 grams sample of copper has a volume of 14 cubic centimeters. What is the density of copper?

    Let suppose that mass of the copper sample is distributed uniformly in its volume, then we shall use the following definition of density ([tex]\rho[/tex]), in grams per cubic centimeter:

    [tex]\rho = \frac{m}{V}[/tex] (1)

    Where:

    [tex]m[/tex] – Mass, in grams.

    [tex]V[/tex] – Volume, in cubic centimeters.

    If we know that [tex]m = 124.6\,g[/tex] and [tex]V = 14\,cm^{3}[/tex], then the density of the sample of copper is:

    [tex]\rho = \frac{m}{V}[/tex]

    [tex]\rho = 8.9\,\frac{g}{cm^{3}}[/tex]

    The density of copper is 8.9 grams per cubic centimeter.
