The value 14 cm 3 is said to be the partial molar volume of water in ethanol.
3.
The partial molar volumes of the components of a mixture vary with the composition of the mixture, because the environment of the molecules in the mixture changes with the composition.
4.
In contrast to ideal solutions, the volumes in the case of regular solutions are no longer strictly additive but must be calculated from partial molar volumes that are a function of x 1.
5.
Where the index i iterates the components, N i is the mole fraction of the i th component in the solution, P is the pressure, the index T refers to constant temperature, V i, aq is the partial molar volume of the i th component in the solution, V i, cr is the partial molar volume of the i th component in the dissolving solid, and R is the universal gas constant.
