To calculate the freezing point of an ideal dilute solution of a single, nondissociating solute in a solvent, the minimum information one must know is
I.The molality (of the solute).
II.The molality (of the solute) and the freezing-point-depression constant of the solvent.
III.The freezing point of the pure solvent.
IV.The molecular weight of the solute.
V.The weight of the solvent.
A) II, III only
B) II only
C) II, III, IV
D) II, III, V
E) I only

Quizplus · Accepted Answer

To calculate the freezing point depression, you need the molality of the solute and the freezing-point-depression constant of the solvent. Additionally, you need the freezing point of the pure solvent to determine the new freezing point.
