    \[10\,g\]of hydrogen and 64 g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be

    A)  3 mol  

    B)  4 mol   

    C)  1 mol  

    D)  2 mol

    Correct Answer: B

    Solution :

     \[\underset{1\,mol}{\mathop{{{H}_{2}}}}\,+\underset{0.5\,mol}{\mathop{\frac{1}{2}{{O}_{2}}}}\,\xrightarrow[{}]{{}}\underset{1\,mol}{\mathop{{{H}_{2}}O}}\,\] \[\frac{10}{2}=5mol\frac{64}{32}=2\,mol\,4mol\] Because oxygen is the limiting reagent, hence 4 moles of\[{{H}_{2}}O\]formed.
