    Osmotic pressure of insulin solution at 298 K is found to be 0.0072 atm. Hence, height of water column due to this pressure is [given d\[(Hg)=13.6\,\,g/mL\]]

    A)  0.76cm          

    B)  0.70cm

    C)  7.4 cm           

    D)  76 cm

    Correct Answer: C

    Solution :

    \[p=0.0072\] atm \[=0.0072\times 76\,\,cm\]of Hg \[=0.0072\times 76\times 13.6\,\,cm\] of mercury column Also,      \[p=h\times 1\,\,cm\] of water column \[\therefore \] \[h\times 1=0.0072\times 76\times 13.6\,cm\] or \[h=7.4\,cm\]
