    For an electrolyte solution of \[0.05\text{ }mol\text{ }{{L}^{-1}}\] the conductivity has been found to be \[0.0110\text{ }S\text{ }c{{m}^{-1}}\] The molar conductivity is

    A) \[0.055\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]

    B) \[550\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]

    C) \[0.22\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]

    D) \[220\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]

    Correct Answer: D

    Solution :

    [d] \[{{\Lambda }_{m}}=\frac{\kappa \times 1000}{M}=\frac{0.0110\times 1000}{0.05}\] \[=220\text{ }S\text{ }c{{m}^{2}}mo{{l}^{-1}}\]
