    At \[60mL\], the osmotic pressure of urea solution is 500 mm. The solution is diluted and the temperature is raised to \[C{{s}^{+}}\]. The osmotic pressure of dilute solution is \[I{{E}_{1}}\]mm at \[mo{{l}^{-1}}\]. The extent of dilution can be shown as

    A)  \[1.60\times {{10}^{23}}\]

    B)  \[1.60\times {{10}^{15}}\]

    C)  \[1.60\times {{10}^{18}}\]

    D)  \[16.0\times {{10}^{26}}\]

    Correct Answer: A

    Solution :

                    For initial solution, \[N{{i}_{2}}{{O}_{3}}\] \[127\,kJ\]                 \[245.11kJ\]        \[90.71kJ\] After dilution, \[122.55kJ\] \[H{{g}^{2+}}+2C{{l}^{-}}HgC{{l}_{2}},\] \[k=1.65\times {{10}^{3}}\] From Eqs. (i) and (ii), \[H{{g}^{2+}}\] i.e., solution was diluted to 5 times.
