    25g of \[MC{{l}_{4}}\] contains 0.5 mole chlorine then its molecular weight is

    A)  100 g \[mo{{l}^{-1}}\]    

    B)  200 g \[mo{{l}^{-1}}\]

    C)  150 g \[mo{{l}^{-1}}\]    

    D)  400 g \[mo{{l}^{-1}}\]

    Correct Answer: B

    Solution :

    0.5 mole chlorine is present in 25 g of \[MC{{l}_{4}}\] mole chlorine will be present in 50 g of \[MC{{l}_{4}}\] But \[MC{{l}_{4}}\] contain 4 moles of chlorine then, molecular weight of \[MC{{l}_{4}}=4\times 50\] \[=200\,g\,mo{{l}^{-1}}\]
