1.	What is the advantage of using osmotic pressure as compared to other colligative properties for the determination of molecular mass of solute?
Answer» Boiling point and freezing point. ... Both the boiling point elevation and the freezing point depression are PROPORTIONAL to the lowering of VAPOR pressure in a DILUTE solution. Theseproperties are colligative in systems where the SOLUTE is essentially confined to the liquid phase.
