# How many grams of lithium metal are required to react with a 28*g mass of dinitrogen gas?

$6 L i \left(s\right) + {N}_{2} \left(g\right) \rightarrow 2 L {i}_{3} N \left(s\right)$
$L {i}_{3} N \left(s\right) + 3 {H}_{2} O \left(l\right) \rightarrow N {H}_{3} \left(a q\right) + 3 L i O H \left(a q\right)$
