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

Q. Osmotic pressure of a sugar solution at $2 4^{\circ} C$ is 2.5 atmospheres. Determine the concentration of the solution in gram mole per litre.

0.0821 moles/litre

1.082 moles/litre

0.1025 moles/litre

0.0827 moles/litre

Here it is given that
$π = 2.5 a t m, T = 24 + 273 = 297 . K$ ,
$S = 0.0821$ lit. atm. $d e g^{- 1} m o l^{- 1}, C =$ ?
We know that $π = CST$
or $C = \frac{π}{ST}$
$= \frac{2.5}{0.0821 \times 297}$
$= 0.1025$ moles/litre

Q. Osmotic pressure of a sugar solution at 24∘C is 2.5 atmospheres. Determine the concentration of the solution in gram mole per litre.
