The first step to solve this question is to balance the given equation. To do it, make sure that the amount of every element is equal in both, reactants and products.


Mg_3N_2+3K_2O\rightarrow3MgO+2K_3N

Now, use the stoichiometric ratio between the coefficients of potassium oxide and potassium nitride:


14molK_2O\cdot(1molMg_3N_2)/(3molK_2O)=4.66molMg_3N_2

The answer is 4.66moles of magnessium nitride.
