ANSWER:Step 1 of 3
Stoichiometry plays a major role in determining the number of reactants required to produce
certain number of products or vice versa. Stoichiometry can be considered only for a
balanced chemical equation. The mole ratio is also considered for the quantitative analysis
of compounds in the chemical reaction.
