Explanation:

Density:

  • The density of material shows the denseness of that material in a specific given area.
  • A material’s density is defined as its mass per unit volume.
  • Density is essentially a measurement of how tightly matter is packed together.
  • Though the SI unit of density is kg/m³, for convenience we use gm/cm³ for solids, g/ml for liquids, and g/L for gases.

Density = \(\frac{Mass}{Volume}\)

  • Higher the density of metal, the heavier the metal.
  • Gold is the heaviest metal among the following because it has the highest density among the given metals.
