Question

The relative density of lead is 11.3. Its density is ....g cm –3 or . ...kg m –3 .how to convert the units ?take care of the significant figures plz help,,

Answer 1

Relative density = (density of substance) / (density of water)

and Density of water = 1 g/cm^3 or 1000 kg/m^3

So, RD 11.3 = Density of lead / 1 g/cm^3

So, Density of lead = 11.3 g/cm^3

Also, RD 11.3 = Density of lead/1000kg/m^3

So, Density of lead = 11300 kg/m^3
