s Institute.... The salt concentration of the Dead Sea is around 31.5% by mass. This is unusually high and results in a nominal density of 1.24 kg/L. Assuming sodium chloride is the only substance present in the seawater. A) Calculate the molarity and the molality of the solution. B) Assuming an average year-round temperature of -25°C, is this solution (i) unsaturated (ii) saturated or (iii) supersaturated? Why? C) The osmotic pressure of the solution at 25°C is 275.34 atm. Use this information to calculate van't Hoff factor, i of NaCl in this solution. D) Use the value of the van't Hoff factor i obtained in part C above to calculate the freezing point of this NaCl solution. Kr for H₂O = 1.86 °C/m s Institute....
