    5 ml of N HCl, 20 ml of N/2 \[{{H}_{2}}S{{O}_{4}}\] and 30 ml of N/3 \[HN{{O}_{3}}\] are mixed together and volume made to one litre. The normality of the resulting  solution is

    A) \[\frac{N}{5}\]                          

    B) \[\frac{N}{10}\]

    C) \[\frac{N}{20}\]                                    

    D) \[\frac{N}{40}\]

    Correct Answer: D

    Solution :

    \[NV={{N}_{1}}{{V}_{1}}+{{N}_{2}}{{V}_{2}}+{{N}_{3}}{{V}_{3}}\] \[1000\,\,N=1\times 5+\frac{1}{2}\times 20\,\,+\frac{1}{3}\times 30 or\,\,N=\frac{1}{40}\]
