    The answer is D aluminum (density = 2.7g/mc3).

    A density (D) of a substance is a quotient of its mass (m) and its volume (V):

    D = m/V

    It is given:

    m = 13.5 g

    V = 5 cm³

    Therefore:

    D = m/V = 13.5/5 = 2.7 g/cm³

    Among all choices, only aluminum has density of 2.7 g/cm³.
