The S.I. unit of density is ______.

Open in App

Solution

As formula of density is,
$D e n s i t y (ρ) = \frac{m a s s (m)}{V o l u m e (V)}$
The S.I. the unit of density will be the ratio of S.I. unit of mass and volume.

The S.I. unit of mass is kilogram $(k g)$ and S.I. unit of volume is $(m^{3})$ .
So, the S.I. the unit of density will be $k g m^{- 3}$ .
