Question

N2+3H2 gives 2NH3.what is the equivalent mass of nitrogen in NH3?

Answer 1

Equivalent mass of `N` `=14/3`gm

Explanation:

Given reaction is
`N_2 +3H_2 rarr 2NH_3`

Here oxidation state of `N` in`N_2` is 0. Whereas, oxidation state of `N` in`NH_3` is -3.
So, Three electrons are accepted by `N`.
Hence, Valence factor or n-factor `(n_f)` 0f `N` is `3`.

As we know,
Equivalent mass of `N` `=` Molar Mass of `N` `/n_f`

Equivalent mass of `N` `=14/3`gm
