# 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
