          can be calculated from eqs. (3.52). Examples will be given in Sect. 4.4 of this
          chapter.


          4.3      Uncertainties or Errors of Measurement

             Uncertainties of Gibbs excess masses (3.52) as represented by their mean
          square  deviations (MSD)        can be  calculated by applying  the Gauss
          Law of  propagation  of  uncertainty of  error to  eqs.  (3.51)  and  (3.52)
          respectively:












          in view of (3.50) and (3.42, 3.46) we have
























          To provide an overview of all parameters to be measured and uncertainties to
          be considered we list them in a table:
