Question

A coefficient is a number listed before a compound or atom, telling how many of the compounds are needed so that the Law of Conservation of Mass is obeyed. Given the information provided, how many iron (III) sulfide atoms are there? 4 Fe2S3

Answer 1

A coefficient is a number that indicates the number of molecules or atoms of a substance in a chemical equation. In the given example, there are 4 molecules of iron (III) sulfide.

Step-by-step explanation:

A coefficient is a number that is placed in front of a compound or atom in a balanced chemical equation, telling how many of the compounds are needed so that the Law of Conservation of Mass is obeyed. It indicates the number of molecules or atoms of that substance involved in the reaction. In the given example, the coefficient is 4 in front of Fe2S3. This means that there are 4 molecules of iron (III) sulfide in the reaction.
