Chapter 9.5, Problem 9.6SC

Lithium nitride, an ionic compound containing the ${\text{Li}}^{+}$and ${\text{N}}^{3-}$ions, is prepared by the reaction of lithium metal and nitrogen gas. Calculate the mass of lithium nitride formed from 56.0 g of nitrogen gas and 56.0 g of lithium in the unbalanced reaction.

$\text{Li}\left(s\right)+{\text{N}}_2\left(g\right)\to {\text{Li}}_3\text{N}\left(s\right)$
