From an examination of the available ultrasonic and density data, in the case of eleven inorganic melts, the relation between the molar volume (M/p) and sound velocity, V, is found to be MV^2/^3/p=S where S is a constant independent of temperature. The molar sound velocity S is found to be an additive property. The contributions of different ions to the molar sound velocity of a liquid have been evaluated. The variation, of V^2/^3/p with percentage weight of the solute in aqueous solutions for a number of univalent electrolytes, is found to be linear. The linear plots are extrapolated to get the value of V^2/^3/p for 100 percent of the solute. These values are multiplied by the respective values of the molecular weights of the solutes to give the molar sound velocity for the substance-Such extrapolated values have been found to correspond to the molar sound velocity of the substance in the liquid phase.
