The mole ratio would be 4:3
What is the mole ratio?
Mole ratio is the ratio of the stoichiometric number of moles of components of reactions.
From the equation: [tex]4NH_3 + 3O_2 --- > 2N_2 + 6H_2O[/tex]
The mole ratio of [tex]NH_3[/tex] to that of [tex]N_2[/tex] is the ratio of their coefficients. The coefficients are 4 and 3 respectively
Thus, the ratio is 4:3.
