Calculate osmotic pressure of $0.2 \mathrm{M}$ aqueous $\mathrm{KCl}$ solution at $0^{\circ} \mathrm{C}$ if van't Hoff factor for $\mathrm{KCl}$ is $1.83 .\left[\mathrm{R}=0.082 \mathrm{dm}^3\right.$ atm mol$\left.{ }^{-1} \mathrm{~K}^{-1}\right]$
  1. $8.2 \mathrm{~atm}$
  2. $9.4 \mathrm{~atm}$
  3. $10.6 \mathrm{~atm}$
  4. $6.5 \mathrm{~atm}$

Solution

$\begin{aligned} \pi & =\mathrm{iMRT} \\ & =1.83 \times 0.2 \times 0.082 \times 273 \\ & =8.2 \mathrm{~atm}\end{aligned}$
