Question

Relative density of gold is 19.5.The density of water is 1000kg/m3.what will be the density of gold in S.I unit and in g/cc.

Answer 1

The relative density is 19.5 and the density of water is 1000 kg/m3
density of object= RD of the object * Density of liquid
= 19.5*1000
= 19500 kg/m3

Answer 2

Hi there !!

We are given the relative density  as 19.5

We know that ,

Relative density = Density of substance ÷ Density of  water

Density of  water = 1000 kg/m³

Density of substance = Density of  water × Relative density
                                  = 19.5 × 1000
                                  = 19500 kg/m³
 The SI Unit of density is kg/m³.

1 kg/m³ = 0.001 g/cm³
19500 kg/m³ = 19.5 g /cm³
