The density of gold, for example, is about 2.5 times the density of iron, which is about 2.5 times the density of aluminum. Density also reveals something about the phase of the matter and its substructure.

Density (volumetric mass density or specific mass) is the ratio of a substance's mass to its volume. The symbol most often used for density is ρ (the lower case Greek letter rho), although the Latin letter D (or d) can also be used: [1] where ρ is the density, m is the mass, and V is the volume.
Learn the core concepts and math behind density in chemistry. This tutorial explains the density formula, units, and real-world applications to help students master this essential property of matter.
Density, mass per unit volume of a 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 gram per cubic centimeter. For example, the density of water is 1 gram per cubic centimeter.
Key Takeaways: Density Density is mass per unit volume, meaning how much matter packs into a given space. The formula for density is ρ = m/V. Density is an intensive property, so it does not depend on the size of the sample. Common units include g/mL, g/cm³, and kg/m³.
