Densities of aqueous solutions of sodium bromide at the molalities (0.09855, 0.49997, and 1.0001) mol.kg(-1) were determined at 1 K temperature intervals from T = 278.15 K to T = 338.15 K. The densities were used in the evaluation of the apparent molar volumes, the cubic expansion coefficients, the apparent molar expansibilities and the second derivatives of the volume with respect to temperature. Properties of sodium bromide solutions which were determined in volumetric and calorimetric measurements are discussed and compared.
