Question

Q3.Define relative density. Write its unit. Density of silver is 10.8 x 103Kg/m3. Calculate the relative density of silver if the density of water is 1000kg/m3.

Answer 1

Relative density = Density relative to water 
      Density of silver = relative density * density of water
                          = 10.8 * 1 gm/cm³ = 10.8 gm/cm³
                  in SI units,  10.8 * 1000 kg/m³ = 10, 800

Answer 2

Answer:

Density of silver = 10.8 * 10³ kg/m³

Explanation:

Given,

Relative density of silver is 10.8

The density of water is 10³ kg /m³.

To find: density of silver in Si unit?

Solution:

Relative density is defined as the ratio of density of a substance to the density of water.

i.e Relative density = density of silver / density of water

or, density of silver = Relative density of silver * density of water

or, Density of silver = 10.8 * 10³ kg / m³
