Problem: A glucose solution contains 71.8 g of glucose (C6H12O6) in 471 g of water.Determine the freezing point of the solution.

FREE Expert Solution

We have to determine the freezing point of a solution made by dissolving 71.8 g of glucose (C6H12O6) in 471 g of water.


When a nonvolatile solute is dissolved in a solvent, the freezing point of the resulting solution is always lower than the freezing point of pure solvent. This property of solutions is called the freezing point depression.


We will solve this problem through these steps:

Step 1: Find the molality of glucose in solution.

Step 2: Use the formula for freezing point depression to calculate freezing point of solution.


Step 1: Find the molality of glucose in solution.

Molality is calculated using this formula:

molality = moles of solutekg of solvent
