When heated, lithium reacts with nitrogen to form lithium nitride: 6Li( s ) + N 2 ( g ) 2Li 3 N( s ) What is the theoretical yield of Li 3 N in grams...

When heated, lithium reacts with nitrogen to form lithium nitride:

6Li(s) + N2(g) → 2Li3N(s)

What is the theoretical yield of Li3N in grams when 12.7 g of Li is heated with 34.7 g

of N2?

 g

If the actual yield of Li3N is 6.01 g, what is the percent yield of the reaction?
