Give reason for the following
Mesasurenent of osinotic pressure method is preferred for the determination of molar masses of macmolecules such as proteins and polymers.

Explanation

To answer the question regarding why the measurement of osmotic pressure method is preferred for the determination of molar masses of macromolecules such as proteins and polymers, we can break down the reasoning into several key points:

### Step-by-Step Solution:

1. **Definition of Osmotic Pressure**:
- Osmotic pressure (π) is the pressure required to prevent the flow of solvent into a solution through a semipermeable membrane. It is directly proportional to the molarity (C) of the solute in the solution.

2. **Osmotic Pressure Equation**:
...
