Question

Explain density and relative density and write formulae.

Answer 1

Density of a substance is defined as mass of a substance per unit of its volume i.e.

Density = $\frac{massofsubstance}{Volumeofsubstance}$

And Relative density is ratio of density of substance to that of water i.e.

Relative density = $\frac{Densityofsubstance}{Densityofwater}$
