✦ Synopsis

Isopiestic vapor-pressure measurements were made for Lu2(SO4)3(aq) at molalities from (0.35379 to 0.66478) mol•kg -1 and for H2SO4(aq) at molalities from (0.27470 to 0.70512) mol•kg -1 at the temperature T=298.15 K using KCl(aq) as the isopiestic reference standard; results for Lu2(SO4)3(aq) extend to slightly above saturation. These measurements encompass the water activity ranges aw of 0.9902EawE0.9783 and 0.9902EawE0.9741, respectively. Molality analyses used for previous solubility, density (J.
