Quantity of 1.5g brass containing Cu,Zn reacts with `3M,HNO_(3)` solution, the following reactions takes place
`Cu +HNO_(3) rarr Cu^(2+) +NO_(2) +H_(2)O`
`Zn +H^(+) +NO_(3)^(-) rarr NH_(4)^(+) +ZN^(2+) +H_(2)O` (un balanced)
The liberated `NO_(2)(g)` is found to occupy 1.04 litre at `25^(@)C` and 1 atm pressure. Now answer the following question
Weight of `NH_(4)NO_(3)` formed in the reaction is

Options

A. `0.046g`
B. `0.183g`
C. `0.092g`
D. `0.55g`

Answer

A

Explanation

`4Zn +10 HNO_(3) rarr NH_(4)NO_(3) +4Zn (NO_(3))_(2) +3H_(2)O`
no of moles of zinc `=4 xx` no of mol of `NH_(4)NO_(3)`
`:.` weight of `NH_(4)NO_(3) = (0.0023 xx 80)/(4)`
