$$50$$ 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

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 $$24\ V$$.
