Answer : The correct option is, 4.0 mole

Explanation : Given,

Moles of lithium = 12 mole

The given balanced chemical reaction is:


6Li+N_2\rightarrow 2Li_3N

By the stoichiometry we can say that, 6 moles of Li react with 1 mole of
N_2 to give 2 moles of
Li_3N

As, 6 moles of lithium react to give 2 moles of lithium nitride

So, 12 moles of lithium react to give
(12)/(6)* 2=4 moles of lithium nitride

Therefore, the number of moles of lithium nitride produced will be 4.0 mole.
