Answer : The mole ratio of \(NH_3\) to \(N_2\) is, 4 : 2
Explanation :
Mole ratio : It is defined as the ratio of number of moles of the substances whose ratio is to be calculated.
The given balanced chemical reaction is :
\(4NH_3+3O_2\rightarrow 2N_2+6H_2O\)
By stoichiometry of the reaction we can say that,
4 moles of ammonia reacts with the 3 moles of oxygen to produce 2 moles of nitrogen and 6 moles of water.
Hence, the mole ratio of \(NH_3\) to \(N_2\) is, 4 : 2
