the coefficients in a balanced chemical equation provide the mole-to-mole stoichiometry among the reactants and products. the molar mass (in g/mol) can be used as the conversion factor between moles and the mass of a substance. thus, the balanced equation and molar masses can be used in conjunction with one another to calculate the masses involved in a reaction.

Unit conversion factors are used to convert between units of grams and moles.

In stoichiometry mass of a substance is calculated from the inter-conversion between moles and grams using conversion factors.

That is, to calculate the mass of a compound or an element in a chemical equation we multiply the number of moles by the molar mass of the compound.

Therefore, in stoichiometry, moles can be calculated from the mole ratio of reactants and products involved or by dividing mass of a compound by the molar mass.
