Question

What is the molar ratio of Li to N2 in the given reaction? 6Li + N2 → 2Li3N

Answer 1

The modern ration is 6:1

Answer 2

Answer: The mole ratio of $Li$ to $N_2$ is  6: 1

Explanation:

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.

$6Li+N_2\rightarrow 2Li_3N$

According to the stoichiometry:

6 moles of $Li$ are combining with 1 mole of $N_2$ to give 2 moles of $Li_3N$

Thus the mole ratio of $Li$ to $N_2$ is  6: 1
