JEE Main 2026 (02 April Shift 2)
Question
Solution A is prepared by dissolving g of a protein (molar mass g mol) in L of water at K. Its osmotic pressure is bar. Solution B is made by dissolving g of same protein in L of water at K. Osmotic pressure of solution B is bar. Entire solution of A is mixed with entire solution of B at same temperature. The osmotic pressure of resultant solution is bar. and respectively are:
L bar mol K
L bar mol K

Correct answer
A
Step-by-step explanation
Osmotic pressure is given by
For solution A:
bar
For solution B:
bar
For the resultant solution (mixture of A and B):
Total mass of protein g
Total volume of solution L
bar
Therefore, bar.
Answer:
For solution A:
bar
For solution B:
bar
For the resultant solution (mixture of A and B):
Total mass of protein g
Total volume of solution L
bar
Therefore, bar.
