The mass of \( \mathrm{Mg}_{3} \mathrm{~N}_{2} \) produced if \( 48 \mathrm{gm} \) of \( \mathrm{Mg} \)
\( \mathrm{P} \)
metal is reacted with \( 34 \mathrm{gm} \mathrm{NH}_{3} \) gas is
W
\[
\mathrm{Mg}+\mathrm{NH}_{3} \rightarrow \mathrm{Mg}_{3} \mathrm{~N}_{2}+\mathrm{H}_{2}
\]
(A) \( \frac{200}{3} \mathrm{gm} \)
