Densities and apparent molar volumes of LiCl(aq) and NaBr(aq) at molalities from 0.0025 mol·kg −1 to 3.0 mol·kg−1, temperatures from 604.4 K to 725.5 K, and pressures from 18.5 MPa to 38.0 MPa

Abstract

A vibrating-tube densitometer was used for measuring differences in densities between water and LiCl(aq) and NaBr(aq) at molalities from 0.0025 mol·kg−1 to 3.0mol·kg−1, at temperatures from 604.4 K to 725.5 K, and pressures from 18.5 MPa to 38.0 MPa. The density differences and the derived apparent molar volumes are tabulated.
