JEE Main 2020 (04 Sep Shift 2)

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 x×10-3 atm. x is ________ (nearest integer)

Correct answer
167

Step-by-step explanation

π=iCRT

On mixing two solution πfinal=π1V1+π2V2V1+V2

πfinal=0.1×1+0.2×23

            =0.1+0.43=0.53=5003×100-3atm

So,      X=167
