What is the freezing point of a solution of 0.5 mol of libr in 500 ml of water? (kf = 1.86°c/m) –1.86°c –7.44°c –5.58°c –3.72°c

Explanation:

The freezing point depression in a solvent is a colligative property: it depends on the number of solute particles.

The equation to predict the freezing point depression in a solvent is:
