ABSTRACT
The experimental data of densities for the N2O4 + H2O + HNO3 system were measured with the N2O4 mole fractions from 0 to 0.15 and H2O mole fraction from 0.08 to 0.33 at 278.15 K, 283.15 K, 288.15 K, and 293.15 K. The excess molar volumes (VE) at 293.15 K were obtained from the experimental results for this ternary system. The experimental results were correlated using an empirical equation. The average absolute deviations (AADs) between the calculated and experimental data were calculated.
