Volume concentration

In chemistry, the volume fraction φi is defined as the volume of a constituent Vi divided by the volume of all constituents of the mixture V prior to mixing:[1]

\phi_i = \frac {V_i}{V}

The SI-unit is m3/m3.

Volume fraction is also called volume concentration in ideal solutions where the volumes of the constituents are additive (the volume of the solution is equal to the sum of the volumes of its ingredients).

The sum of all volume fractions of a mixture is equal to 1:

\sum_{i=1}^{N} V_i = V ; \qquad \sum_{i=1}^{N} \phi_i = 1
