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

    A)  \[100g\text{ }mo{{l}^{-1}}\]

    B)  \[200\text{ }g\text{ }mo{{l}^{-1}}\]

    C)  \[150g\text{ }mo{{l}^{-1}}\]

    D)  \[400g\text{ }mo{{l}^{-1}}\]

    Correct Answer: B

    Solution :

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