Question

$50$ ml of a certain sample of $H_2{O}_2$ gives $1200$ ml of $O_2$ at STP. The volume strength of $H_2{O}_2$ is:

• A. 22.4 V
• B. 20 V
• C. 24 V
• D. 11.2 V

Answer 1

Answer: (C)

24 V

It is given that $50$ ml of a certain sample of $H_2{O}_2$ gives $1200$ ml of $O_2$ at STP.

Volume strength is the volume of oxygen at STP given by one volume sample of hydrogen peroxide on heating.

If $50$ ml of $H_2{O}_2$ gives $1200$ ml of $O_2$, then volume strength will be $=\frac{1200}{50}=24V$

Hence, the volume strength of $H_2{O}_2$ is $24V$.
