Osmotic pressure of a sugar solution at 2 4 o C is 2.5 atmospheres. Determine the concentration of the solution in mole per litre.

Options

  1. A0.0821 moles/litre
  2. B1.082 moles/litre
  3. C0.1025 moles/litre
  4. D0.0827 moles/litre

Correct answer

C. 0.1025 moles/litre

Step-by-step solution

Here it is given that π = 2.5   atm,   T = 24 + 273 = 297   K ,   S = 0.0821   lit .  atm   K − 1   mo 1 − 1 C   =   ? We know that π = CST or C = π ST = 2.5 0.0821 × 297 = 0.1025 moles/litre
