The relative densities (d-d0) of NaCl, MgCl2, Na2SO4, and MgSO4 aqueous solutions have been determined at 1 atm with a vibrating flow densimeter from 0.001 to 1.5 m and from 0 to 35 °C. The data have been combined with our earlier measurements at temperatures up to 55 °C and fitted to equations of the following form (precisions better than 15 × 10-6 g cm-3): d-d0 = Am + Bm3/2 + Cm2 + Dm5/2, where d and d0 are the densities of solution and pure water, respectively, m Is the molality, and A, B, C, and D are temperature-dependent parameters. The equations agree well with the results of other workers.
