This implies that any pure sample of a compound, no matter the source, will always consist of the same elements that are present in the same ratio by mass. For example, pure water will always contain hydrogen and oxygen in a fixed mass ratio (a gram of water consists of approximately 0.11 grams of hydrogen and 0.88 grams of oxygen, the ratio is 1:8).<\/p>\n\n\n\n<p>The law of constant proportions is often referred to as Proust\u2019s law or as the law of definite proportions. An illustration describing the mass ratio of elements in a few compounds is provided below. The ratio of the number of atoms of each element is provided below the mass ratio. For example, in a\u00a0nitrogen dioxide\u00a0(NO<sub>2<\/sub>) molecule, the ratio of the number of nitrogen and oxygen atoms is 1:2 but the mass ratio is 14:32 (or 7:16).<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" src=\"https:\/\/mdr.foobrdigital.com\/wp-content\/uploads\/2022\/06\/Law-Of-Constant-Proportions-700x350-1.png\" alt=\"\" class=\"wp-image-5048\" title=\"Law of Constant Proportions\"\/><\/figure>\n\n\n\n<p>In the year 1794, the French chemist Joseph Proust formulated the law of constant proportions from his work on sulphides, metallic oxides, and sulfates. This law was met with a lot of opposition in the scientific community in the 18th century. The introduction of\u00a0Dalton\u2019s atomic theory\u00a0favoured this law and a relationship between these two concepts was established by the Swedish chemist Jacob Berzelius in the year 1811.<\/p>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>What is the Law of Constant Proportions?
