You might as well ask why are addition and subtraction central to accounting.
Explanation:
All chemical reactions conserve (i) mass, and (ii) charge. It is convenient when we consider the stoichiometry of a chemical reaction to consider the mass in terms of moles, which necessarily represents a number of reactant and product particles, and thus also a mass of same. And this is why educators go to such lengths in teaching stoichiometry. If the reaction ain’t balanced with respect to mass and charge, it ain’t a model of reality. There should be many answers here that deal with stoichiometry.
