Osmotic pressure exerted by a solution prepared by dissolving one gram mole of a solute in 22.4 litres of a solvent at 0°C will be _______________ atmosphere?
Correct answer: B. 1
- A. 0.5
- B. 1
- C. 1.5
- D. 2
Explanation
Using π = CRT, the concentration is 1/22.4 mol/L and RT at 0°C is approximately 22.4 L·atm/mol. Their product is therefore 1 atm for an ideal dilute solution.
