The volume of the mixture prepared by taking 1.158 mol and 0.842 mol of water and ethanol, respectively, was measured as 68.16 cm3 at 25 ° C. Since the partial molar volume of water in the mixture is 16.98 cm3 / mol, find the partial molar volume of ethanol. Since the densities at 25ᴼC for pure water and ethanol are given as 0,9970 g / cm3 and 0,7852 g / cm3, respectively, find the volume change during the preparation of the mixture and interpret the result. (MSu: 18 g / mol; Methanol = 46 g / mol)
