Interpretation:
The given compounds have to be arranged in decreasing order of their freezing points.
Concept introduction:
The temperature at which a liquid turn into solid, when cooled, is termed as its freezing point.
Molality is defined as the number of moles of solute per kilogram of solvent.
Molality is inversely related to the freezing point of a solvent;higher the molality, lower is the freezing point, and vice versa.
Molality is directly related to depression in freezing point, as
Freezing point depression is a colligative property observed in solutions that results from the introduction of solute molecules to a solvent.
Strong electrolytes dissociate completely, weak electrolytes partially dissociate, and nonelectrolytes do not dissociate at all.

- Arrange the following aqueous solutions in order of decreasing freezing point. (The last three are all assumed to dissociate completely into ions in water.) (a) 0.20 m ethylene glycol (nonvolatile, nonelectrolyte) (b) 0.12 m K2SO4 (c) 0.10 m MgCl2 (d) 0.12 m KBrarrow_forwardCalculate the molality of a solution made by dissolving 115.0 g ethylene glycol, HOCH2CH2OH, in 500. mL water. The density of water at this temperature is 0.978 g/mL. Calculate the molarity of the solution.arrow_forwardWater at 25 C has a density of 0.997 g/cm3.
