Question

Write the colligative property which is used to find the molecular mass of macromolecules

Answer 1

Osmotic pressure measurement is preferred for molar mass determination because :

 (a) even in dilute solution the osmotic pressure values are appreciably high and can be measured accurately.

 (b) osmotic pressure can be measured at room temperature.

Answer 2

Hello dear,

● Answer -
Osmotic pressure is preferred colligative property to determine molecular mass of macromolecules.

● Explanation -
- There are 4 types of colligative properties -
- lowering of vapor pressure
-  depression in freezing point
- elevation of boiling point
- osmotic pressure

From these, osmostic pressure is used for molecular mass determination because
- It can be measured with precision even in dilute solutions.
- Variation in osmotic pressure is follows colligative law.


Hope this helped you...
