Solution: Lithium nitride, Li3N is an interesting salt. It is a fast ion conductor and it has also been studied as an anode material for batteries. Lithium nitride is produced according to the following reaction: 6 Li (s) + N 2 (g) → 2 Li3N (s) If the percent yield of the reaction at 85.00 oC is 65.28% and the reaction yields 18.326 g of lithium nitride from an experimental quality of lithium, how much lithium nitride would theoretically be expected in the experiment? A. 3.560 g B. 11.96 g C. 28.07 g D. 27.89 g E. 18.25 g
