Question

The osmotic pressure of a solution of NaCl is 0.10 atm and that of a glucose solution is 0.20 atm. The osmotic pressure of a solution formed by mixing 1 L of the sodium chloride solution with 2 L of the glucose solution is  atm. x is  (nearest integer)

Strategy:
 When two solutions are mixed, the total osmotic pressure of the mixture is determined by the total number of moles of solute particles and the final total volume. We first calculate the effective moles from each solution and then find the new pressure.

Step 1: Calculate the effective moles of particles () from each solution
Using :
- For NaCl solution:
  - , 
  
- For glucose solution:
  - ,

Step 2: Calculate total moles and total volume
- Total moles () = 
- Total volume () =
