To find the mole ratio of hydrogen to nitrogen, first check to see if the equation is balanced.
On the reactant side of the equation there are 2 atoms of Nitrogen and 6 of Hydrogen.
On the product side of the equation there are 2 atoms of Nitrogen and 6 of Hydrogen.
Therefore the equation is balanced.
Use the coefficients to find the mole ratio. Nitrogen has no coefficient so it's a 1, and Hydrogen has a 3. The ratio of Hydrogen to Nitrogen is therefore 3 to 1.
