Calculate the strength of 10 volume solution of hydrogen peroxide.

Explanation

10 volume solution of `H_(2)O_(2)` means that 1 L of this `H_(2)O_(2)` solution will give 10 L of oxygen at STP.
`underset(68g)underset(2xx34g)(2H_(2)O_(2)(l))tounderset(22.7L" at "STP)(O_(2)(g)+H_(2)O(l))`
On the basis of above equation 22.4 L of `O_(2)` is produced from 68 g `H_(2)O_(2)` at STP 10 L of `O_(2)` at STP is produced from `(68xx10)/22.4g=30.36g`
`~~30gH_(2)O_(2)`
Therefore, strength of `H_(2)O_(2)` in 10 volume `H_(2)O_(2)` solution = 30.36 g/L = 3% `H_(2)O_(2)` solution.
