The relative density of lead is 11.3. Its density is ....g cm^–3 or ....kg m^–3.

Here the relative density of lead is given. We have to find the density of lead.

Relative density of lead = -------------- (1)

Density of lead = Relative density of lead × Density of water

Relative density of lead = 11.3

Density of water = 1 g/cm³ = 1000 kg/m³

Substituting the above density values in equation (1).

Density of lead = 11.3 × 1 g/cm³

= 11.3 g/cm³

We have to find the density of lead in kg/m³ also.

Substituting the value of density of water in kg/m³ in equation (1)

Density of lead = 11.3 × 1000 kg/m³

= 1.13 × 10⁴ kg/m³

The density of lead = 11.3 g/cm³ or 1.13 × 10⁴ kg/m³
