Question

How many moles of N₂ are essential for generating 0.08 moles of Li₃N in the given reaction?

6Li + N₂ 2Li₃N

0.013 moles

0.04 moles

0.08 moles

0.16 moles

0.48 moles

Answer 1

Each mole of N₂ generates 2 moles of Li₃N. Thus,
0.08 moles of Li₃N will require:
0.08 / 2
= 0.04 moles of N₂

The second option is correct.
