• question_answer If ${{H}_{2}}{{O}_{2}}$ is ?5. 6 volume?, then A)  it is 1.7% weight by volume               B)  it is 1 N C)  Both [a] and [b]        D)  None of these

$2{{H}_{2}}{{O}_{2}}\xrightarrow{\,}\,2{{H}_{2}}O+{{O}_{2}}$ 5.6 volume means 1 mL of HOg solution gives $5.6\,\,mL\,{{O}_{2}}$ at STP. $\because$ 22400 mL ${{O}_{2}}$ at NTP is obtained from $68\,g\,{{H}_{2}}{{O}_{2}}$. $\therefore$ 5.6 mL ${{O}_{2}}$ at NTP is obtained from $\frac{68\times 5.6}{22400}$. ${{H}_{2}}{{O}_{2}}=0.017\,g\,{{H}_{2}}{{O}_{2}}$ $\therefore$ It is 1.7% And normally $\frac{\text{Volume}\,\text{strength}}{5.6}=1N$
