Question:
The molecular mass of NaCl as determined by osmotic pressure measurement is
The molecular mass of NaCl as determined by osmotic pressure measurement is
Updated On: Jul 7, 2022
- 58.5
- less than 58.5
- more than 58.5
- unpredictable
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
NaCl undergoes dissociation in an aqueous solution. As such number of particles in solution increases, the magnitude of colligative property increases, molecular mass decreases.

Osmosis
Osmosis is a passive process and happens without any expenditure of energy. It involves the movement of molecules from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane.
There are three different types of solutions:
- Isotonic Solution is one that has the same concentration of solutes both inside and outside the cell.
- Hypertonic solution is one that has a higher solute concentration outside the cell than inside.
- Hypotonic solution is one that has a higher solute concentration inside the cell than outside.
