The osmotic pressure of a solution increases as a. the boiling point of the solution decreases. b. the amount of solvent in the solution increases. c. the number of particles of solute in the solution increases. d. the freezing point depression constant of the solution decreases.

The osmotic pressure of a solution is a colligative property, which means that it depends on the number of particles of solute in the solution.

Formula: Osmotic pressure = MRT, where M is the molarity of the solution, R is the universal constant of ideal gases and T is the absolute temperature of the solution.

So, the answer is the option .: the osmotic pressure of a solution increases as the number of particles of solute in the solution increases.
