Answer:
Correct Answer: D
Solution:
$ [H_2O_2\to H_2O+\frac{1}{2}O_2]\times 2 $
$ \underset{68g}{\mathop{2H_2O_2}}\to 2H_2O+O_2 $ 22.4 litre at N.T.P. $ \because $ 22.4 litre $ O_2 $ at N.T.P. obtained by 68 gm of $ H_2O_2 $ \ 10 litre $ O_2 $ at N.T.P. obtained by $ \frac{68}{22.4}\times 10=30.35gm/litre $ \ 1000 ml $ O_2 $ at N.T.P. obtained by = 30.35 gm \ 100 ml $ O_2 $ at N.T.P. obtained by $ =\frac{30.35}{1000}\times 100=3.035% $
