The mass of the reactants must be equal to the mass of the products. The total number of moles of the reactants must also be equal to the total number of moles of the products.

The mass of the reactants must be equal to the mass of the products. The total number of moles of the reactants can be more or less than the total number of moles of the products.

Reason: mass is conserved in a chemical reaction (closed system), but the number of moles can change depending on stoichiometry (especially for reactions that change gas molecule count).
