The law of constant composition states that the elements forming a particular compound always combine in the same proportions. This means that a specific compound will always have the same ratio of elements, regardless of its source or method of preparation. For example, water will always have a ratio of two hydrogen atoms to one oxygen atom, no matter where it comes from or how it was made. This law helped chemists develop a systematic approach to understanding and identifying different compounds.
