Question
A 0.9720 M aqueous solution of NaCl has a density of 1.03625 g/cm3 at 25 °C,
Calculate the molality of this solution. (You will also need the density of pure water at 25° C which equals to 0.997044 g/cm3 .)
Calculate the apparent molar volume of the above solution.
What quantities will be obtained in a plot of apparent molar volume vs the square root of the molality?
How will these quantities be used to determine the partial molar volumes of the aqueous NaCl solution.
