Question

The S.I unit of density is kg/m³. Give reasons.

Answer 1

1. The mass of an object contained per unit volume is known as density.
2. If the mass of an object be M and its volume be V, then the density (D) of the object will be Density (D) = $\frac{\mathrm{Mass}\left(\mathrm{M}\right)}{\mathrm{Volume}\left(\mathrm{V}\right)}$
3. S.I unit of density = $\frac{\mathrm{S}.\mathrm{I}\mathrm{unit}\mathrm{of}\mathrm{mass}\left(\mathrm{kg}\right)}{\mathrm{S}.\mathrm{I}\mathrm{unit}\mathrm{of}\mathrm{volume}\left({\mathrm{m}}^3\right)}$= kg/m³
