In CGS system, mass is measured in grams
and volume in cubic centimetres. Therefore, the 8. Co
unit of density in CGS system is g/cm' or gem. 9. Sily
In SI system, mass is measured in 10. L
kilograms and volume in cubic metres. Therefore, 11. G

Answer 1

Answer:

mass of a unit volume of a material substance is called density.

The formula of density is d=M/V.

Answer 2

Answer:

The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: where ρ is the density, m is the mass, and V is the volume.

density= mass÷ volume
