Q12) Distinguish between density and relative density.
Solution:
Density -
It’s the ratio of mass to volume; Density = \frac{mass\ }{volume}=\frac{M}{V}
Units are g\ cm^{-3}
Density in kg\ m^{-3} = R.D = 1000
Relative Density -
It is the ratio of density of substance to density of water.
It is a pure quantity. It has no units
R.D = Density in g\ cm^{-3}
R.D = Density in kg\ m^{-3} /1000
