The densities and sound velocities at T = (288.15, 293.15, 298.15, 303.15 and 308.15) K were measured for aqueous solutions of glycine, trimethylamine-N-oxide, taurine and N-methylacetamide. From these data, the apparent molar volumes, V the apparent molar isentropic compressions, KS,, and the Passynski hydration numbers of solutes were determined. The concentration dependencies of the calculated quantities, their limiting values and temperature characteristics are discussed in terms of solute-solvent and solute-solute interactions. The obtained data clearly show strong hydration of the molecules of glycine, trimethylamine-N-oxide and taurine. Opposite effect, i.e. weak interactions with water molecules, is found for N-methylacetamide.
