In chemistry, the molar concentration, is defined as the amount of a constituent divided by the volume of the mixture. It is also called molarity,
Amagat’s law or the Law of Partial Volumes of 1880 describes the behaviour and properties of mixtures of ideal (as well as some cases of non-ideal)
Atomic packing factor
In crystallography, atomic packing factor (APF), packing efficiency or packing fraction is the fraction of volume in a crystal
The Clausius–Clapeyron relation, named after Rudolf Clausius and Benoît Paul Émile Clapeyron, is a way of characterizing a discontinuous phase transition
Number density is an intensive quantity used to describe the degree of concentration of countable objects. Volume number density is the number of specified
The density of a material is defined as its mass per unit volume. For a pure substance the density has the same numerical value as its mass concentration.
