MHT CET 2025 Chemistry question
Calculate the concentration of an aqueous solution of non electrolyte at 300 K if its osmotic pressure is 12 atm. [R = 0.0821 atm dm K mol]
Answer: (B)
Solution
For a non-electrolyte (van't Hoff factor ), the osmotic pressure is . So \dfrac{π}{RT}\dfrac{12\ atm}{0.0821\ \mathrm{atm dm^3 K^{-1} mol^{-1}}×300\ K}\dfrac{12}{24.63}$
