“The relative lowering of vapour pressure of a solution is equal to the mole fraction of the solute present in the solvent.” The realtive lowering of vapour pressure of a solvent is directly proportional to the number of moles of solute only and is independent of the nature of solute.

Explanation:
Relative lowering of vapour pressure is a colligative property, which depends on the number of solute particles present in a solution. Here's why it is directly proportional to the mole fraction of solute:
Mole fraction of solute:
- The relative lowering of vapour pressure is directly proportional to the mole fraction of the solute in the solution. This is because the presence of solute particles in the solution reduces the number of solvent particles available to escape into the vapor phase.
- According to Raoult's law, the lowering of vapor pressure is proportional to the mole fraction of the solute in the solution.
- The more solute particles present in the solution, the greater the reduction in the vapor pressure of the solvent.
Therefore, the mole fraction of solute plays a crucial role in determining the relative lowering of vapor pressure in a solution. Other factors such as the density of the solution, mass of the solvent, and color of the solution do not directly affect this colligative property.
