    Faraday's constant, F equals

    A)  96,5000

    B)  \[\text{96},\text{5}000\text{k}{{\text{g}}^{-\text{1}}}\]

    C)  \[\text{96},\text{5}00\text{ kg }{{\text{C}}^{-\text{1}}}\]

    D)  \[\text{96},\text{5}00\text{ C mo}{{\text{l}}^{-\text{1}}}\]  

    Correct Answer: D

    Solution :

     Since, \[1\] Farady is the charge on \[{{N}_{A}}\] electrons, where \[{{N}_{A}}\] the Avogadro's number is the number of molecules in \[1\,\,gm\] mole of the substance, so the unit of Faraday should be coulomb/mole.
