    The amount of \[{{H}_{2}}{{\text{O}}_{2}}\] present in 1 litre of \[1.5N{{H}_{2}}{{\text{O}}_{2}}\] solution, is:

    A) 25.5 g              

    B) 3.0 g 

    C) 8.0 g                

    D) 2.5 g

    Correct Answer: A

    Solution :

    [a] Molecular weight of \[{{H}_{2}}{{O}_{2}}=34\] Equivalent weight of \[{{H}_{2}}{{O}_{2}}=17\] \[\therefore \] 1 L of 1 \[N\,{{H}_{2}}{{O}_{2}}\] has =17g of \[{{H}_{2}}O\] \[\therefore \] 1 L of \[1.5N\,{{H}_{2}}{{\text{O}}_{2}}\] has \[=1.5\times 17=25.5g\,of\,{{H}_{2}}{{O}_{2}}\]
