What is another word for law of multiple proportions?
Pronunciation: [lˈɔː ɒv mˈʌltɪpə͡l pɹəpˈɔːʃənz] (IPA) 
The law of multiple proportions is a fundamental principle in chemistry that describes the relationship between the masses of elements in compounds. Synonyms for this law include the law of definite proportions, the law of constant composition, and the law of multiple ratios. These terms all refer to the same idea that the ratio of elements in a compound is fixed and can be expressed as whole numbers. This law is essential in chemistry as it allows us to predict the composition of compounds and study chemical reactions. It was first discovered by French chemist Joseph Louis Proust in the late 18th century, and it remains one of the key principles of modern chemistry.
