    A metal oxide is reduced by heating it in a stream of hydrogen. It is found that after complete reduction, \[3.15\,\,g\] of the oxide have yielded \[1.05\] of the metal. We may deduce that

    A)  the eq. weight of the metal is 8

    B)  the atomic weight of the metal is 8

    C)  the atomic weight of the metal is 4

    D)  the eq. weight of the metal is 4.

    Correct Answer: D

    Solution :

    Equivalents of metal                                 = equivalents of oxygen: Thus\[\frac{1.05}{E}=\frac{3.15-1.05}{8}\],                           \[E=4\]
