Question

Osmotic pressure of a solution depends upon the number of moles of ______ dissolved in a definite volume of solution and not upon the ______ of ______.

Answer 1

Osmotic pressure of a solution depends upon the number of moles of solute dissolved in a definite volume of solution and not upon the nature of solute.

Explanation:

Osmotic pressure is a colligative property, meaning it depends only on the quantity (number of particles) of solute, not on the type (nature) of solute. Whether it’s sugar or salt, if the number of solute particles is the same, the osmotic pressure will also be the same (assuming ideal behaviour).
