Standard Chemical Potential and Activity Coefficient on Different Concentration Scales

Considering a similar approach and using Equations 1.5 through 1.7, the reader should be able to easily derive the relationship between y and y j [y = y (1 + /55.51)]. Any other relations between the standard chemical potential or between the activity coefficients on the different concentration scales can be obtained using the same approach. Most of these equations are given in Ref. [3]. 

Note that the standard chemical potential has the same dimensions as chemical potential, that is, J mol, and activity and activity coefficient are dimensionless.
