Answer 2

Answer:

“Density of a substance is mass per unit volume. It is a derived quantity. The unit of density in SI system is kilograms per meter ^-3and in CGS. system, it is gcm^-3"

e.g. density of water =1×10^3. kgm^-3

e. g. density of steel =7.8×10^3. kgm^-3

e. g. density of air =1.3×10^-3. kgm^-3
