The best colligative property to use in determining the molecular weight of very large molecules is:

Question

Quizplus · Accepted Answer

Osmotic pressure is directly proportional to the number of solute particles in a solution, regardless of their identity or size. Therefore, it is the best colligative property to use in determining the molecular weight of very large molecules, as it is not affected by the size of the solute molecules. Boiling point elevation and freezing point depression are also commonly used to determine molecular weight, but they may not be as accurate for very large molecules as they are for smaller molecules. Vapor pressure lowering and Henry's Law are not directly related to molecular weight and are not commonly used for molecular weight determination.
