Define the terms, 'osmosis' and 'osmotic pressure'. What is the advantage of using osmotic pressure as compared to other colligative for the determination of molar masses of solutes in solutions?

Explanation

### Step-by-Step Solution:

1. **Define Osmosis**:
- Osmosis is the process by which solvent molecules move from a region of lower solute concentration to a region of higher solute concentration through a semi-permeable membrane. This movement continues until there is an equal concentration of solute on both sides of the membrane.

2. **Define Osmotic Pressure**:
- Osmotic pressure is the external pressure that must be applied to a solution to prevent the inward flow of solvent molecules through the semi-permeable membrane. It is a measure of the tendency of a solvent to move into a solution via osmosis.
