Jakobe Wilkinson · Answer 1

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.
