A. `3.00 %`
B. `4.045%`
C. `2.509%`
D. `3.035%`

Answer

d

Explanation

`[H_(2)O_(2) rarr H_(2)O+(1)/(2) O_(2)]xx2`
`underset(68g)(2H_(2)O_(2))2H_(2)O+O_(2)22.4 `litres `N.T.P. `
`:' 22.4` litres `O_(2)` at `N.T.P.` obtained by `68 g `of `H_(2)O_(2)`
`:. 10` litres `O_(2)` at `N.T.P.` obtained by
`=(68)/(22.4)xx10=30.35g // L`
`:. 1000ml O_(2)` at `N.T.P. `obtained by `=30.35g`
`:. 100 ml O_(2) `at `N.T.P.` obtained by
`=(30.35)/(1000)xx100=3.035 %`
