Densities of 1-propanol + water + lithium nitrate mixtures have been measured with an oscillating-tube densimeter over a large range of concentrations of the salt and 1-propanol. at 288.15, 298.15, 308.15, and 318.15 K. From these densities, apparent molar volumes of lithium nitrate in I -propanol + water mixtures have been calculated for each temperature, and apparent molar volumes at infinite dilution have been evaluated. An empirical correlation for partial molar volumes of lithium nitrate in I -propanol + water mixtures with solvent composition and temperature has been derived.
