Density of potassium bromide, KBr(aq)

Table 1. Estimated values of absolute density (g/cm3) of aqueous potassium bromide solutions {KBr + 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.
