The Amagat equation of state or Amagat's law [1], applies to mixtures where each component is an ideal gas. It states that the volume of the mixture is the sum of the volumes of each component.
For n {\displaystyle n} components,
V t o t a l = ∑ i = 1 n V i = V 1 + V 2 + . . . + V n {\displaystyle V_{total}=\sum _{i=1}^{n}V_{i}=V_{1}+V_{2}+...+V_{n}}
