Question 5

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

Answer

Mass of zinc = 438.6 g

Volume of zinc = 86 cm3

Density of zinc = ?

Density of Zinc=Mass of ZincVolume of Zinc=438.686=5.1 g cm−3\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.
