  • question_answer
    The vapour density of a chloride of a metal is \[81.5\,\,(H=1)\] and the chloride contains \[34.46%\] metal. The specific heat of the metal is\[0.115\]. The molecular formula of chloride is

    A) \[MC{{l}_{2}}\]                 

    B) \[{{M}_{2}}C{{l}_{3}}\]

    C) \[MC{{l}_{3}}\]                 

    D) \[MC{{l}_{4}}\]

    Correct Answer: C

    Solution :

    Vapour density of chloride\[=81.5\] Molecular mass\[=2\times 81.5=163\] Metal weight\[34.46%\]of Chlorine weight\[=65.54%\]of\[163=106.8\] Number of chlorine atom\[=\frac{106.8}{3.5}=3\] Thus, molecular formula of chloride\[MC{{l}_{3}}\].
