A 1.1287% (weight percent) solution of a salt with M, = 162.5 g mol1 was prepared at 25 °C. The density of the prepared solution was 1.00886 g cm 3 The density of water at 25 °C is 0.99707 g cm3, and the density of the crystalline salt was 2.730 g cm(-3). What is the molar volume of the crystalline salt? Estimate the partial molar volume of the salt at infinite dilution. Are (a) and (b) the same? Why?
