WebRelative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is … WebAug 19, 2024 · Density is the ratio of the mass of an object to its volume. (1.12.1) density = mass volume (1.12.2) D = m V. Density is usually a measured property of a substance, so its numerical value affects the significant figures in a calculation. Notice that density is defined in terms of two dissimilar units, mass and volume.
