Osmotic pressure of insulin solution at $298 \mathrm{~K}$ is found to be $0.0072 \mathrm{~atm}$. Hence, height of water column due to this pressure is $[$ given $\mathrm{d}(\mathrm{Hg})=13.6 \mathrm{~g} / \mathrm{mL}]$
  1. $0.76 \mathrm{~cm}$
  2. $0.70 \mathrm{~cm}$
  3. $7.4 \mathrm{~cm}$
  4. $76 \mathrm{~cm}$

Solution

$\mathrm{P}=0.0072 \mathrm{~atm}$
$=0.0072 \times 76 \mathrm{~cm}$ of $\mathrm{Hg}$
$=0.0072 \times 76 \times 13.6 \mathrm{~cm}$ of mercury column
$=h \times 1$ of water column
$h=0.0072 \times 76 \times 13.6 \mathrm{~cm}$
$=7.4 \mathrm{~cm}$ ,
