They indicate the number of molecules in a substance.
Coefficients are used to balance chemical equations. These numbers are placed in front of the chemical formulas to ensure that the number of atoms on both sides of the equation are equal.
Coefficients in front of chemical formulas are used to balance chemical equations by ensuring that the number of each type of atom is the same on both sides of the equation. By adjusting the coefficients, you can keep the law of conservation of mass intact, showing that no atoms are created or destroyed during a chemical reaction.
Count the atoms in each substance in the reactants and products. (Apex)
The number placed in front of a chemical formula in a chemical equation is called a coefficient. Coefficients are used to balance chemical equations by ensuring that the number of atoms of each element is the same on both sides of the equation.
The numbers placed immediately before formulas of compounds and/or elements involved in the reaction are called "coefficients" and those placed immediately after element symbols, depressed below the typographical line of the element symbol are called "subscripts". The subscripts show the number of atoms of a particular element in a formula unit of a molecule or other compound.

Coefficients are used to balance equations because if you change the subscript, than you would change the substance.
Writing a chemical reaction with symbols: Ex.: NaCl + AgNO3 = AgCl (s) + NaNO3 A mathematical (digital) system for the writing of chemical equations exist but it is rarely used.
