Concept explainers
(a)
Interpretation:
The freezing point and boiling point of solution should be calculated.
Concept Introduction:
The molality of solution is defined as number of moles of solute in 1 kg of solvent.
It is mathematically represented as follows:
Here, n is number of moles of solute and M is mass of solvent.
From the mass, number of moles can be calculated as follows:
Here, m is mass and M is molar mass.
The freezing point is directly proportional to the molality of the solution.
Or,
Here,
Similarly, the boiling point is directly proportional to the molality of the solution.
Or,
Here,
