The properties of dilute or ideal soltions which depend only upon the concerntration of the solute in the solution and to other characteristics are known as colligative properties. There are in all four such properties i.e., relative lowering in vap[our pressure, osmotic pressure, elevation in boiling point tmperature and depression in freezing point temperature. All of them them in calculating the observed molar mass of the solute which is inversely propertional to the coligative property involved. Out of these, osmotic pressure may be regarded as the best for the determination of molecular mass of the solute. According to Van't Hoff theory of dilute solution. pi=CRT , where pi is the osmotic pressure while C is the molar concentration of the solution.
