which one of these factors most affects colligative properties of solutions? a density b luster c molarity d…

Brief Explanations:

Colligative properties of solutions depend on the number of solute particles in a given amount of solvent. Molarity is a measure of the number of moles of solute per liter of solution, directly related to the number - of - solute - particle count. Density, luster, and volume do not have a direct impact on colligative properties in the same way.

Answer:

C. molarity
