    Answer:

    1.06 moles of nitrogen gas will react with 3.20 moles of magnesium in the container.

    Explanation:

    3 Mg (s) + 1 N_2 (g) \rightarrow 1 Mg_3N_2 (s)

    Moles of magnesium heated = 3.20 mol

    According to reaction, 3 moles of magnesium reacts with 1 mole of nitrogen gas, then 3.20 moles of magnesium will react with:

    =\frac{1}{3}\times 3.20 mol=1.07 \text{ mol of }N_2

    1.06 moles of nitrogen gas will react with 3.20 moles of magnesium in the container.
