Interpretation:
The statement, “Molality is used to calculateboiling point elevation and freezing point depression, whereas molarity is used to calculate the osmotic pressure.”is to beexplained.
Concept introduction:
The molarity of a solution is expressed as the number of moles of the solute present per liter of the solution.
The molality of a solution is expressed as the number of moles of the solute present per kilogram of the solvent.
Osmotic pressure is the pressure required to stop the process of osmosis.
Boiling point elevation is aphenomenon in which the presence of a solute increases the boiling point of the solvent.
Freezing point depression is a phenomenon in which the presence of a solute decreases the freezing point of the solvent.

- Create a flow diagram, similar to those used in the example problems of this chapter, that outlines the determination of the molar mass of a compound from freezing-point depression measurements. Clearly indicate the data needed for this determination.arrow_forwardDistinguish between a strong electrolyte, a weak electrolyte, and a nonelectrolyte. How can colligative properties be used to distinguish between them? What is the vant Hoff factor? Why is the observed freezing-point depression for electrolyte solutions sometimes less than the calculated value? Is the discrepancy greater for concentrated or dilute solutions?arrow_forwardThe solubility of ethylene (C2H4) in water at 20 C and 0.300 atm pressure is 1.27 104 molal. (a) Calculate the Henrys law constant for this gas in units of molal/torr. (b) How many grams of ethylene are dissolved in 1.00 kg water at 20 C if the pressure of the gas is 500 torr?arrow_forward
