    The molar conductivity of a\[0.5\frac{mol}{d{{m}^{3}}}\]solution of \[AgN{{O}_{3}}\]with electrolytic conductivity of \[5.76\times {{10}^{-3}}S\text{ }c{{m}^{-1}}at\text{ }298K\]

    A)  \[2.88\text{ }Sc{{m}^{2}}/mol\]         

    B)  \[11.52\text{ }Sc{{m}^{2}}/mol\]

    C)  \[0.086\text{ }Sc{{m}^{2}}/mol\]       

    D)  \[28.8\text{ }Sc{{m}^{2}}/mol\]

    Correct Answer: B

    Solution :

    \[{{\Lambda }_{m}}=\frac{k\times 100}{m}=\frac{5.76\times {{1}^{-3}}\times 1000}{0.5}\] \[=11.52\,Sc{{m}^{2}}/mol\]
