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

Answer :

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/cm^{3} = 1000 kg/m^{3}

Substituting the above density values in equation (1).

Density of lead = 11.3 × 1 g/cm^{3}

= 11.3 g/cm^{3}

We have to find the density of lead in kg/m^{3} also.

Substituting the value of density of water in kg/m^{3} in equation (1)

Density of lead = 11.3 × 1000 kg/m^{3}

= 1.13 × 10^{4} kg/m^{3}

The density of lead = 11.3 g/cm^{3} or 1.13 × 10^{4} kg/m^{3}
