Answer: b) the number of particles present in the solution
Explanation: Colligative properties are the properties which depends on the amount or the number of particles.
Colligative properties include relative lowering in freezing point,elevation in boiling point, depression in freezing point and osmotic pressure.
[tex]\pi =CRT[/tex]
[tex]\pi[/tex] = osmotic pressure
C= concentration which depends on the amount or the moles of solute irrespective of its identity.
R= solution constant
T= temperature
