  • question_answer
    What will be the normality of a solution containing 4.9 g. \[{{H}_{3}}P{{O}_{4}}\] dissolved in 500 ml water   [MP PMT 2003]

    A)                 0.3         

    B)                 1.0

    C)                 3.0         

    D)                 0.1

    Correct Answer: A

    Solution :

           \[N=\frac{w\times 1000}{E\times \text{volume}\,\text{in}\,\,ml.}\], \[E=\frac{98}{3}=32.6\]                                 \[N=\frac{4.9\times 1000}{32.6\times 500}=0.3N\].
