100 mL each of 1NH_(2)O_(2) " and " 11.2 V H_(2)O_(2) solution are mixed, then the resultant solution will be :

Answer»

`3M H_(2)O_(2)`
`0.5 N H_(2)O_(2)`
`25.5 g//L H_(2)O_(2)`
`2.55 g//L H_(2)O_(2)`

Solution :`11.2V H_(2)O_(2)-=(11.2)/(5.6)N H_(2)O_(2) i.e., 2N H_(2)O_(2)`
`N_(1)V_(1)+N_(2)V_(2)=N_(R )(V_(1)+V_(2))`
`1xx100+2xx100=N_(R )xx200`
`N_(R )=(3)/(2)=1.5`
Strength `=N xx " Equivalent MASS"`
`=1.5xx17=25.5 g//L`
