    What will be the normality of resulting solution in which 5 mL of M HCl, 20 mL of \[\frac{M}{2}\] \[{{H}_{2}}S{{O}_{4}}\] and 30 mL of \[\frac{M}{3}HN{{O}_{3}}\] are mixed together and volume made to 1 L?

    A) \[\frac{M}{40}\]

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

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

    D) \[\frac{M}{5}\]

    Correct Answer: A

    Solution :

    [a]
    \[MV={{M}_{1}}{{V}_{1}}+{{M}_{2}}{{V}_{2}}+{{M}_{3}}{{V}_{3}}\]
    or           \[M\times 1000=1\times 5+\frac{1}{2}\times 20+\frac{1}{3}\times 30\]
    or                     \[M=\frac{1}{40}\]
