Theoretical density
Webb13 mars 2024 · In general it is not necessary to weigh exactly 1 cm 3 of a material in order to determine its density. We simply measure mass and volume and divide volume into mass: (1) Density = mass volume or (2) ρ = m V where ρ = density m = … Webbdensity, 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 …
