A piece of zinc of mass 438.6 g has a volume of 86 cm³. Calculate the density of zinc.

Mass of zinc = 438.6 g

Volume of zinc = 86 cm³

Density of zinc = ?

$\text{Density of Zinc} = \dfrac{\text{Mass of Zinc}}{\text{Volume of Zinc}} \\[1em] = \dfrac{\text{438.6}}{\text{86}} = 5.1 \text{ g cm}^{-3}$

So, Density of Zinc = 5.1 g cm^-3.
