The Law of Definite Proportions states that in any given chemical compound, the elements are always present in the same proportion by mass. This means that regardless of the amount of oxygen present in the reaction container, the ratio of hydrogen to oxygen in water is always 1:8 by mass, which is consistent with the Law of Definite Proportions.
