Question

the density of metal is 10.8 x 10 raise to 3 kg per metre cube find the relative density of the metals

Answer 1

"We know that, relative density of a substance = Density of the substance / Density of water Relative density of silver

= Density of silver / Density of water10.8

= Density of silver / 1000 kg m-3Density of silver

= 10.8 * 1000 kg m-3 = 10800 kg m-3

"

Answer 2

Density of metal = 10.8 × 10^3 kg/m^3

We know that
Relative density(RD) of a substance = density of the substance/density of water

Density of water = 10^3 kg/m^3

RD of metal = 10.8×10^3 / 10^3 = 10.8

Relative density of metal is 10.8.
