  • question_answer
    Volume of water needed to mix with 10 ml  10N \[HN{{O}_{3}}\] to get 0.1 N \[HN{{O}_{3}}\]                [UPSEAT 2003]

    A)                 1000 ml

    B)                 990 ml

    C)                 1010 ml

    D)                 10 ml

    Correct Answer: B

    Solution :

           \[{{N}_{1}}{{V}_{1}}={{N}_{2}}{{V}_{2}}\]            \[10\times 10=0.1\,(10+V)\]                 \[V=\frac{10\times 10}{0.1}-10=1000-10=990\,ml.\]
