    What mass of \[{{H}_{2}}(g)\] is needed to reduce 192 gm. of \[Mo{{O}_{3}}\] to metal? [At. wt. of Mo = 96]

    A) 8 gm.

    B) 16 gm.

    C) 32 gm.

    D) None of these

    Correct Answer: A

    Solution :

    [a] Equivalent of \[Mo{{O}_{3}}=\frac{M}{6}=\frac{144}{6}=24\] Equivalent of \[{{H}_{2}}:\frac{192}{24}=\frac{{{W}_{{{H}_{2}}}}}{1}\Rightarrow {{W}_{{{H}_{2}}}}=8gm.\]
