Density is a measure of mass divided by volume.
density is mass of the substance for a unit volume
[tex] density (kg m^{-3} )= \frac{mass (kg)}{volume( m^{3}) }[/tex]
Density is also referred to as ρ.
A large mass spread over a small volume is said to have a high density. Some substances could have a large mass spread over a very large volume, those are said to have a small density.
