Question
Chapter 17, Problem 9DQ
Interpretation Introduction
Interpretation: Whether the molarity or molality is dependent on temperature or not needs to be explained and the reason of using of molality in the equations describing freezing point depression and boiling point elevation needs to be explained.
Concept introduction: Molality and molarity both are ways of expressing concentration. Molarity is the number of moles of solute in 1L of solution and molality is the number of moles of solute in 1 kg of solvent.
