Question
  1. According to the balanced chemical question below, how many grams of Li 3N can be formed from 3.39 moles of Li? Assume an excess of nitrogen gas. The molar mass of lithium nitride (Li 3N) is 34.83 g/mol.
    6 Li (s) + N 2 (g) ? 2Li 3N (s)
       
    0.451 g
       
    39.4 g
       
    32.6 g
       
    25.4 g
       
    236 g
Expert Solution
Step 1

Reaction involved: 

6 Li(s) + N2(g) ------> 2 Li3N(s) 

We are assuming that Nitrogen is present in excess, so, limiting reagent will be Lithium 

Given data: 

Moles of Li3N = 3.39 mol

Molar mass of lithium nitride = 34.83g/mol
