    Equivalent weight of a bivalent metal is 37.2. The molecular weight of its chloride is

    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 its chloride is\[MC{{l}_{2}}\] Hence, molecular weight of\[MC{{l}_{2}}\]                                                    \[=74.4+2\times 35.5\]                                                    \[=145.4\]
