    How many coulombs of electricity are consumed when 100 mA current is passed through a solution of\[AgN{{O}_{3}}\]for half an hour during an electrolysis experiment?

    A)  108                                       

    B)  18000

    C)  180                                       

    D)  3000

    Correct Answer: C

    Solution :

                    \[Q=i\times t\] Here,    \[i=100\text{ }mA=\frac{1}{10}-A\] \[i=\frac{1}{2}h=\frac{1}{2}\times 60\times 60=1800s\] \[Q=\frac{1}{10}\times 1800=180\,C\]
