Worked examples

Density of a metal sample

A sample has a mass of 2.7 kg and a volume of 0.001 m³. Find its density.

  1. 1Step 1: Use ρ = m / V.
  2. 2Step 2: Substitute m = 2.7 kg and V = 0.001 m³.
  3. 3Step 3: Divide to obtain 2700 kg/m³.

Result: 2,700 kg/m³

Mass from density and volume

A liquid has a density of 1 g/cm³ and a volume of 250 cm³. Find its mass.

  1. 1Step 1: Use m = ρ × V.
  2. 2Step 2: Substitute ρ = 1 g/cm³ and V = 250 cm³.
  3. 3Step 3: Multiply to obtain 250 g.

Result: 250 g
