WebMar 28, 2024 · Updated on March 28, 2024. Mass is a scientific term used to describe the density and type of atoms in any given object. The SI unit of mass is the kilogram (kg), though mass can also be measured in pounds (lb). To quickly understand the concept of mass, think of a pillowcase filled with feathers and a similar pillowcase filled with bricks. WebDensity (volumetric mass density or specific mass) is the substance's mass per unit of volume.The symbol most often used for density is ρ (the lower case Greek letter rho), 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. In …
