Answer

Explanation:

Step1: Analyze the mole ratio

From the balanced equation (6\text{Li}+\text{N}_2\rightarrow2\text{Li}_3\text{N}), the mole ratio of (\text{Li}) to (\text{Li}_3\text{N}) is (6:2 = 3:1).

Step2: Calculate the moles of lithium nitride

Let (x) be the moles of (\text{Li}_3\text{N}). Using the mole ratio (\frac{\text{mol Li}}{\text{mol Li}_3\text{N}}=\frac{3}{1}). Given (\text{mol Li} = 12) mol. Then (x=\frac{12}{3}) mol.

Answer:

A. (4.0) mol
