How many moles of glucose would be needed to lower the freezing point of one kg of water 3.72°C?

Explanation:

Lowering the freezing point of a solvent, when a nonvolatils solute is added, is a colligative property that follows the equation:

Where:

Then, you can calculate the molality of the solution:

Clear m:

Since molality is the number of moles per kg of solvent, you would need 2 moles of glucose to lower the freezing point of one kg of water 3.72ºC.
