    A solution of \[A{{l}_{2}}{{\left( S{{O}_{4}} \right)}_{3}}\,\{d=1.253\,g/ml\text{ }\!\!\}\!\!\text{ }\] contain \[22\,%\] salt by weight. The molarity,  normality and molality of the solution is

    A) 0.805 M, 4.83 N, 0.825 m

    B) 0.825 M, 48.3 N, 0.805 m

    C) 4.83 M, 4.83 N, 4.83 m

    D) None

    Correct Answer: A

    Solution :

    \[Molarity\,\,=\,\,\frac{%\,\times 10\times d}{GMM}\] \[=\,\,\,\frac{22\times 10\times 1.253}{342}\,=\,0.805\,\,M\] \[Normality\,\,=\,\frac{%\times 10\times d}{GEM}\] \[=\,\,\frac{22\times 10\times 1.253}{342/6}\,=\,4.83\,N\] \[Molality\,\,=\,\,\frac{22\times 1000}{342(100-22)}\,\,=\,\,0.825\,m\]
