The number density (symbol: n or ρN) is an intensive quantity used to describe the degree of concentration of countable objects (particles, molecules, phonons, cells, galaxies, etc.) in physical space: three-dimensional volumetric number density, two-dimensional areal number density, or one-dimensional linear number density. Population density is an example of areal number density. The term number concentration (symbol: lowercase n, or C, to avoid confusion with amount of substa… Web3 nov. 2024 · We can then rearrange this equation to express the mass in terms of density and volume: m = \rho V m = ρV. Finally, by rearranging the equation one final time, we can calculate the volume of an object if the mass and density are known: V = \frac {m} {\rho} V = ρm. This density mass volume calculator contains all three of these equations ... WebLead. Lead is a heavy metal that is denser than most common materials.
