Answer: The mole ratio of hydrogen to ammonia is 3 : 2
Explanation:
Mole ratio is defined as the ratio of number of moles of the substances whose ratio is to be calculated.
In a chemical reaction, the stoichiometric coefficients represents the number of moles.
For the given chemical reaction of production of ammonia follows:
\(N_2+3H_2\rightarrow 2NH_3\)
By stoichiometry of the reaction:
1 mole of nitrogen reacts with 3 moles of hydrogen to produce 2 moles of ammonia.
So, the mole ratio of hydrogen to ammonia in a given chemical reaction is 3 : 2
