# If 100*mL of ammonia gas are decomposed into its constituent elements what volumes of dinitrogen, and dihydrogen would result?

$N {H}_{3} \left(g\right) \rightarrow \frac{1}{2} {N}_{2} \left(g\right) + \frac{3}{2} {H}_{2} \left(g\right)$
And so at STP, if $100 \cdot m L$ of ammonia are decomposed according to the given equation, $50 \cdot m L$ of dinitrogen, and $150 \cdot m L$ dihydrogen will result.
