\(50\) 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

Answer: C
It is given that \(50\) ml of a certain sample of \(H_2O_2\) 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 \(H_2O_2\) gives \(1200\) ml of \(O_2\), then volume strength will be \(= \dfrac {1200}{50}= 24\ V\)

Hence, the volume strength of \(H_2O_2\) is \(24\ V\).
