This ratio reflects the chemical composition of water, where each water molecule consists of two hydrogen atoms bonded to one oxygen atom. Since the atomic masses of hydrogen and oxygen are 1 and 16 respectively, the ratio of their masses ...
The consistent elemental ratio is significant because it allows for the prediction and control of chemical reactions. It forms the basis of stoichiometry, enabling scientists to determine the quantities of reactants and products involved in a reaction.
Lavoisier’s observations provided evidence for the Law of Definite Proportions, which states that a compound always contains the same elements in the same proportions by mass. This contributed to the development of the atomic theory and the understanding of chemical ...
It means that the ratio of the masses of the elements in a compound remains constant regardless of the source or method of preparation. For example, in water, the ratio of hydrogen to oxygen is always 1:8 by mass.
