Question

. Relative density of gold is 19.3. The density of water is 10.3 kg/m3. What is the density of gold in S.I units?

Answer 1

Relative density = Density of substance / Density of water

Relative density = 19 .3

Density of water = 1000 kg /m³

Hence ,
density of substance = Relative density x Density of water

= 19.3 x 1000
= 19300 kg/m³

The si unit of density is kg/m³

Answer 2

. The Correct Answer is 19.3 x 103 kg/m3. Relative density is the ratio of a density of substance (the mass of the unit volume) to the density of reference material. Density of Gold(in SI unit) = 19300 kg/m³ or 19.3 × 103 kg/m3.
