Find the concentration of `1.6N` solution of `H_(2)O_(2)` in terms of volume.

Answer

9

Explanation

`because` Equivalent of `H_(2)O_(2)` in 1 litre solution `=1.6`
`therefore w_(H_(2)O_(2))` in 1 litre solution `=1.6xx(34)/(2)=27.2 g`
`2H_(2)O_(2)rarr2H_(2)O+O_(2)`
`therefore` Volume of `O_(2)` obtained by `1000 mL`
`H_(2)O_(2)` solution`=(22400xx27.2)/(68)=8960 mL`
`therefore` Volume strength of `H_(2)O_(2)=(8960)/(1000)=8.96approx9.0`
