  • question_answer
    Equivalent weight of a bivalent metal is 37.2. The molecular weight of its chloride is                  [MH CET 2003]

    A)                 412.2     

    B)                 216

    C)                 145.4     

    D)                 108.2

    Correct Answer: C

    Solution :

               Equivalent weight of bivalent metal = 37.2                    \[\therefore \] Atomic weight of metal \[=37.2\times 2=74.4\]                    \[\therefore \] Formula of chloride \[=MC{{l}_{2}}\]                    Hence, molecular weight of chloride                                 \[(MC{{l}_{2}})=74.4+2\times 35.5=145.4\]
