| Abstract: | In present paper vapor pressures of glycine aqueous solutions were measured at vari-ous concentrations and three temperatures.In terms of Gibbs-Duhem equation and the re-lation between the osmotic coefficient of olvent and the activity coefficient of solute activi-ty coefficients of glycine in water were determined.Mixing excess free energies were also calculated. |
