Density of nitric acid, HNO3(aq)
Table 1. Estimated values of absolute density (g/cm3) of aqueous
nitric acid solutions {HNO3 + H2O) as function of electrolyte
molality m and temperature T (at pressure p = 1 bar). Values in the table are consistent with the
density of pure water calculated with the IAPWS-95 equation of state.
