Question

Which of the following solutions of glucose in water will have the lowest freezing point?

(The molar mass of glucose is 180 g/mol.)

Answer 1

B

Step-by-step explanation:

Colligative properties are properties that depend on the amount of substance present.

Freezing point is a colligative property hence it depends on the number of moles of the glucose present in solution. The bigger the concentration of the glucose molecules, the greater the freezing point depression. So, the largest freezing point depression is observed for the solution having the highest concentration of glucose.
