    The specific conductivity of  \[N/10\text{ }KCl\] solution at \[{{20}^{o}}C\] is  \[0.0212\text{ }oh{{m}^{-1}}\text{ }c{{m}^{-1}}\] and the  resistance of cell containing this solution at\[{{20}^{o}}C\]  is 55 ohm. The cell constant is

    A)  \[2.173\text{ }c{{m}^{-1}}\]      

    B)  \[1.166\,c{{m}^{-1}}\]        

    C)                                                         \[4.616\text{ }c{{m}^{-1}}\]       

    D)         \[3.324\text{ }c{{m}^{-1}}.\]

    Correct Answer: B

    Solution :

    We know that specific conductance = cell constant \[\times \] conductance \[\Rightarrow \] Cell constant = Resistance \[\times \] specific conductance \[=0.0212\times 55\] \[1.166\,c{{m}^{-1}}\]
