The combined expanded uncertainty of the density (<em>ρ</em>) measurements at the 95 % confidence level with a coverage factor of <em>k </em>= 2 was estimated to be <em>U</em>c(<em>ρ</em>) = ±0.3 kg∙m‐3. The measurements were realized with an Anton Paar DMA HPM vibration tube density meter. The system was calibrated using double-distilled water, aqueous NaCl solutions, methanol, toluene and acetone. An equation of state for fitting of the (<em>p</em>, <em>ρ</em>, <em>T</em>) data of aqueous calcium acetate<strong> </strong>was developed as a function of pressure, temperature and molality. After a thorough analysis of literature values and validity of the constructed equation of state, various thermophysical properties, such as isothermal compressibility, isobaric thermal expansibility, differences in isobaric and isochoric heat cap­acities, thermal pressure coefficient and internal pressure at the investigated state parameter int­ervals were calculated.</p> ER -
