Answer:
Correct Answer: B
Solution:
[b]
$ \therefore 22.4 $ litre $ O_2 $ at N.T.P. obtained by 68 gm of $ H_2O_2 $
$ \therefore $ 1 litre $ O_2 $ at N.T.P. obtained by $ \frac{68}{22.4}gm $ of $ H_2O_2 $
$ \therefore 20 $ litre $ O_2 $ at N.T.P. obtained by $ \frac{68}{22.4}\times 20gmofH_2O_2=60.71gmofH_2{O_2} $
$ \therefore 1000mlO_2 $ at N.T.P. obtained by $ =60.71gmofH_2{O_2} $
$ \therefore 100mlO_2 $ at N.T.P. obtained by $ =\frac{60.71}{1000}\times 100=6.071% $ %
