A

`3.00%`

B

`4.045%`

C

`2.509%`

D

`3.035%`

Text Solution

Verified by Experts

The correct Answer is:
D
`[H_2 O_(2) rarr H_(2)O +1/2 O_2] xx 2`
`underset("68 g")(2H_2 O_(2)) rarr 2H_(2)O +O_2 ` 22.4 L at N.T.P.
`:. ` 22.4 L `O_2` at N.T.P. obtained by 68 g of `H_2O_2`
`:. 10 L O_2` at N.T.P. obtained by
`(68)/(22.4)xx10=30.35` g/L
`:.` 1000 mL `O_2` at N.T.P. obtained by = 30.35 g
`:. ` 100 mL `O_2` at N.T.P. obtained by `=(30.35)/1000 xx100 =3.035%`
