In UNIQUAC term, the excess molar volume,
, is assumed to be analogous to that of the excess Gibbs energy, i.e.
(Combinatorial term omitted)
where 
is a different interaction parameter from that of 
in the 
model.
The symmetrically normalized 
(subscript UNIQ is omitted in the following text) needs to be converted to the unsymmetrically normalized value (
) for density calculations in MSE.
Conversion fromto :
Standard state chemical potentials in the two normalizations are related by
(or 
)
which is derived from equality of chemical potentials in two normalizations, and using
