(a)
Interpretation:
The colligative molality of a solution prepared by dissolving one mole of methanol in
Concept Introduction:
Molality:
Molality is defined as the number of moles of solute per
The colligative molality of a solution is the product of number of solute particles per formula unit and molality of solution. This can be represented as given below.
Where,
(a)

Answer to Problem 16.12P
The colligative molality of the resulting solution is
Explanation of Solution
Given that, one mole of methanol is dissolved
The molality of the resulting solution can be calculated as shown below.
For methanol,
Then, the colligative molality will be same as the molality.
Therefore, the colligative molality of the resulting solution is
