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/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
