Question

what to difference between density and relative density of substance. The relative density of silver is 10.8 . if the density of water is 1000kg per metre cube find the density of silver​

Answer 1

Relative density is the ratio of density of a substance to that of water, so the density of silver is equal to 10.8*1000kg/m^3=10800kg/m^3

Answer 2

The density of a subtance is defined as its mass per unit volume P=m/v and the reletive density of a substance is the ratio of its density to the density of water it is also called specific density so Relative density =Ps /Pw so 10.8/1000 so anser will be 0.0108kg/m^
