Question

>>Define density & its mass..???
plzz ans...

Answer 1

hi mate


density:-Density, mass of a unit volume of a material substance. The formula for density is d = M/V, where d is density, M is mass, and V is volume. Density is commonly expressed in units of grams per cubic centimetre. 

mass:-Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied

Answer 2

The density, or more precisely, the volumetric mass 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.
