The volume strength of the `H_(2)O_(2)` solution is :

Options

A. `0.556`
B. `0.448`
C. `0.896`
D. `0.632`

Answer

C

Explanation

`{:(2H_(2)O_(2),to,2H_(2)O + O_(2)),(68 g,,22.4 " litre at N.T.P."):}`
` :. ` Percentage of `H_(2)O_(2) " soln " = 0.272 %`
` :. ` Strength of `H_(2)O_(2) " soln " = 0.00272 gml^(-1)`
` :. 68 g H_(2)O_(2) ` give oxygen at N.T.P. = `22400 ` ml
` :. 0.00272 `g give oxygen at N.T.P. = `(22400)/68 xx 0.00272 = 0.896` ml .
