    At \[18{}^\circ C\], the conductance of\[{{H}^{+}}\] and \[C{{H}_{3}}CO{{O}^{-}}\]at an infinite dilution is 315 and 35 mho\[c{{m}^{2}}\,e{{q}^{-1}}\]respectively. The equivalent conductivity of\[C{{H}_{3}}COOH\] at infinite dilution is __ mho \[e{{m}^{2}}\,e{{q}^{-1}}\]

    A)  280               

    B)  350                            

    C)  315                

    D)       30                              

    Correct Answer: B

    Solution :

    \[{{\lambda }_{\infty }}={{\lambda }_{a}}+{{\lambda }_{c}}=315+35=350\,\text{mho}\,c{{m}^{2}}e{{q}^{-1}}.\] Hence, the correct option is (b).
