Answer:

The answer is "2.5 mole"

Step-by-step explanation:

The reaction for producing
NH_3 can be defined as follows:

Reaction:


N_2+ 3H_2 \rightarrow 2NH_3

According to the above reaction, to produce 2 moles of
NH_3 we need 1 mole of nitrogen:

So, according to the question to produce 5.0 mole
NH_3 the required
N_2:


\Rightarrow \ 5.0 \ mole \ of \ NH_3 * (1 \ mole\ of \ N_2)/(2 \ mole \ of NH_3)\\\\\Rightarrow 5.0 * (1)/(2)\\\\\Rightarrow 2.5\ mole\\

To produce 5.0 mole
NH_3 we need 2.5 mole
N_2
