QUESTION: Relative Density of gold.........(See in Image)

Answer 1

Hi there !!

Relative density = 19.5

Density of Water = 1000 kg/m³

Relative density = Density of substance / Density of Water

Density of substance [ gold ]  = Relative density × Density of Water
                                               = 19.5 × 1000
                                               = 19500 kg /m³

SI Unit of density = kg /m³

1 kg/ m³ = 0.001 g/cm³

So ,
19500 kg /m³ = 19.5 g/cm³

Density of Gold =  19500 kg /m³ =  19.5 g/cm³
