Question

relative density of gold is 19.3 what is its density in S.I

Answer 1

Relative density = Density of Substance ÷ Density of Water

Relative density = 19.3
 
Density of Water = 1000 kg/m³

Density of Gold = Density of Water ×Relative density
                         = 1000 × 19.3
                         = 19300 kg/m³

SI unit of density is kg/m³
