Equivalent weight of NH3 in the change N2 → NH3 is ​

Answer 1

The molecular weight of ammonia is 17.031 g/mol. The charge of nitrogen in ammonia NH3is 3 and charge of hydrogen is 1. To calculate the equivalent weight of nitrogen in ammonia, substitute the values of molecular weight and charge on the above equation. Thus, the equivalent weight of NH3 in the change N2→NH3 is 173.

Answer 2

$\pmb{ \boxed{Equivalent \: weight \: of \: NH_3}} \\ \\ The \: given \: reaction \: is: \\ N_2\rightarrow NH_3 \\ \small{The \: reaction \: denoting \: electrons \: lost/gained \: : }\\ \bf \: N_2+6e^-\rightarrow 2N^{3-} \\ \sf \tiny{As \: per \: the \: above \: equation, \: the \: number \: of \: electrons \: gained \: is \: 3. }\\ \\ \cal \: Molecular \: weight \: of \: NH_3 \\ = \sf 1 (Atomic \: weight \: of \: N) + 3 (Atomic \: weight \: of \: H) \\ = 1 (14) + 3 (1) \\ = 14 + 3 \\ = 17 \\ \\ \tt \: \scriptsize{∴ Equivalent \: weight = \frac{Molecular \: weight}{Number \: of \: e- \: lost \: or \: gained \: per \: mole} }\\ \\ \bf \: Equivalent \: weight = \frac{17}{3}$
