A general formula has been obtained for the number of distinct arrangements of a mixture of any number of different types of molecules each with its own geometric properties. From this are deduced the thermodynamic properties of such mixtures when the energies of mixing are zero. In particular, the generalization of Raoult’s law has been obtained. The technique used is considerably simpler than that previously applied to problems of this type.
