Hydrogen peroxide in aqueous solution de...

Hydrogen peroxide in aqueous solution decomposes on warming to give oxygen according to the equation
`2H_(2)O_(2)(aq)rarr2H_(2)O(l)+O_(2)(g)`
under conditions where 1 mole of gas occupies 24 `dm^(3)`. `100cm^(3)` of XM solution of `H_(2)O_(2)` produces 3 `dm^(3)` of `O_(2)`. Thus, X is :

A

2.5

B

1
