What is the numerical value of osmotic pressure of 1 M urea solution if numerical value of osmotic pressure of 0.5 M urea solution is ' x '
Options
- Ax
- Bx 2
- C2 x
- D3 x
Correct answer
C. 2 x
Step-by-step solution
The osmotic pressure for a solution is determined by = iCRT , where i is the van't Hoff factor, C the molar concentration, R the gas constant, and T the absolute temperature. Since urea is a nonelectrolyte, i = 1 in both cases. For a 0.5 M urea solution, the osmotic pressure is given as x , so x = 1 0.5 RT and thus RT = 2x . For the 1 M solution, ₂ = 1 1 RT = 2x . The osmotic pressure of the 1 M urea solution is 2x .
