How many gram of dihydrogen is required to react with dinitrogen to produce $34 \mathrm{~g}$ of ammonia?

How many gram of dihydrogen is required to react with dinitrogen to produce $34 \mathrm{~g}$ of ammonia?
  1. $6 \mathrm{~g}$
  2. $2 \mathrm{~g}$
  3. $12 \mathrm{~g}$
  4. $3 \mathrm{~g}$

Solution

$N_{2}(g) + 3H_{2}(g) →2NH_{3}(g)$ $(28~g)\quad \quad (6~g) \quad \quad \quad(34~g)$ $28~g$ of $N_2$ reacts with $6~g$ of $H_2$.
