coefficients give the number of atoms involved in a reaction. Second: the coefficients give the number of moles of each substance involved in the reaction.

Step-by-step explanation:

Coefficients are the number present in front of an atom or molecule in a chemical reaction.

For example,
2Na + Cl_(2) \rightarrow 2NaCl

In this reaction 2 in front of Na in reactant side shows 2 moles of sodium atoms are participating. Whereas 2 in front of NaCl in product side shows that 2 moles of sodium chloride is formed.

Therefore, we can conclude that coefficients in a balanced chemical equation tell you the moles of each substance involved in the reaction.
