One mole of `C_(2) H_(5) NH_(2)` react with `HNO_(2)` how many gram of nitrogen is produced

Options

A. 28 gm
B. 30 gm
C. 25 gm
D. 42 gm

Answer

A

Explanation

`underset(1 mole)(C_(2) H_(5) NH_(2)) + underset( 1 "mole") ( HNO_(2)) to underset( 1 "mole" ) (C_(2) H_(5) OH) + underset( 1 "mole" ) ( N_(2) ) + underset( 1 "mole" ) ( H_(2) O)`
As per reaction 1 mole of `N_(2)` gas is produced
1 mole `N_(2)` gas = molar mass of `N_(2)` =28 gm
