Speeds of sound have been measured for aqueous solutions of the nucleosides adenosine, cytidine, and uridine at the temperatures T = (288.15 and 313.15) K and at the pressures p = (10, 20, 40, 60, 80, and 100) MPa. Using the methods described in our previous work, the partial molar volumes at infinite dilution, V2 o Keywords Speed of sound · Partial molar volume · Partial molar isothermal compression · High pressure · Nucleosides · Aqueous solution
