Density of a substance signifies how densely it is packed
with mass. Mathematically it is expressed as “mass per unit volume”
i.e kg/m3
it also termed as “Mass density” and denoted by r.
Density or Mass density, r = m/v
Depending upon the Units of Measurements, the Density is expressed in various units such as “gm/cc”or “kg/ m3
For example water has a Density of “1 gm/cc” or “1000 kg/m3”
