3.6 moles [tex]NH_{3}[/tex] required when each quantity of reactant completely reacts.
The ratio of the mole quantities of any two compounds present in a balanced chemical reaction is known as the mole ratio. A reaction's product yield can be predicted using mole ratios, as can the amount of reactant required to produce a specific amount of result.
The balanced chemical equation is :
[tex]3N_{2} H_{4}[/tex](l) → [tex]4NH_{3}[/tex](g) + [tex]N_{2}[/tex](g)
Given is = 2.6 mol [tex]N_{2} H_{4}[/tex]
As we see, 3 moles of [tex]N_{2} H_{4}[/tex] reacts with 4 moles of [tex]NH_{3}[/tex].
Therefore,
n( [tex]NH_{3}[/tex]) = n( [tex]N_{2} H_{4}[/tex] ) × [tex]\frac{4}{3}[/tex]
n( [tex]NH_{3}[/tex]) = [tex]2.6mol^{*} \frac{4mol}{3mol}[/tex]
n( [tex]NH_{3}[/tex]) = 3.6 moles.
Therefores, 3.6 moles [tex]NH_{3}[/tex] required when each quantity of reactant completely reacts.
