Given information
Given:
- is the molality of the solution and it is defined as the number of moles of solute dissolved in or of solvent.
- Freezing point =
Step-by-step explanation
Step 1.
The formula of Depression of the freezing point is as follows:
........(1)
Here,
- is depression in freezing point,
- is van’t Hoff factor.
- is molal freezing point depression constant, and
- is the molality of the solution i.e. no. of moles of solute dissolved per or of solvent.
The molality of the solution, (given)
Molal freezing point depression constant of water,
Depression in freezing point of solution:
Here,
- is the freezing temperature of the solvent
- is the freezing temperature of the solution
Substituting the values in the above equation as follows:
