Law of multiple proportions,statement that when two elements combine with each other to form more than one compound,the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers. For example,there are five distinct oxides of nitrogen,and the weights of oxygen in combination with 14 grams …

  • Why do no and NO2 follow the law of multiple proportions?

  • Because the ratio of the masses of oxygen turned out to be whole number ratios, then it shows that NO and NO2 follow the law of multiple proportions. The ratio of the masses of oxygen that combined with the fixed mass of hydrogen in H2O and H2O2 shows a whole number ratio.

  • What is an example of the law of multiple proportions?

  • This is a worked example chemistry problem using the Law of Multiple Proportions. Two different compounds are formed by the elements carbon and oxygen. The first compound contains 42.9% by mass carbon and 57.1% by mass oxygen. The second compound contains 27.3% by mass carbon and 72.7% by mass oxygen.

  • What is an example of a chemistry problem with multiple proportions?

  • Dr. Helmenstine holds a Ph.D. in biomedical sciences and is a science writer, educator, and consultant. She has taught science courses at the high school, college, and graduate levels. This is a worked example of a chemistry problem using the law of multiple proportions. Two different compounds are formed by the elements carbon and oxygen.

  • Are the data consistent with the law of multiple proportions?

  • Show that the data are consistent with the law of multiple proportions. The law of multiple proportions is the third postulate of Dalton’s atomic theory. It states that the masses of one element which combine with a fixed mass of the second element are in a ratio of whole numbers.

  • What is the law of definite proportions?

  • The law of definite proportions was first put forward by the French chemist Joseph Louis Proust in 1779. The discovery that mass was always conserved in chemical reactions was soon followed by the law of definite proportions, which states that a given chemical compound always contains the same elements in the same proportions by mass.

  • What is the law of constant proportions in chemistry?

  • The law of constant proportions states that chemical compounds are made up of elements that are present in a fixed ratio by mass. 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. Which postulate of Dalton鈥檚 theory was correct?

  • What is Proust’s law of definite composition?

  • French chemist Joseph Proust proposed the law of definite composition or proportions based on his experiments conducted between 1798 and 1804 on the elemental composition of water and copper carbonate. It stated that chemical compounds are formed of constant and defined ratios of elements, as determined by mass.

  • What is Richter’s law of definite proportions?

  • In 1792, Richter proposed the law of definite proportions, which gave evidence for the existence of atoms. Richter found that the ratio by weight of the compounds consumed in a chemical reaction was always the same. It took 615 parts by weight of magnesia ( MgO ), for example, to neutralize 1000 parts by weight of sulfuric acid.

    Law of multiple proportions, also known as Dalton s Law, states that whenone element combines with another to form more than one compound, the mass rations of the elements in the compounds are simple whole numbers of each other. 鈥?So remember a compound is just two elements together. Why is the law of multiple proportions important?

Figure 1. Carbon can form two different compounds with oxygen.

  • What is the law of definite proportions?

  • The Law of Definite Proportions states that a chemical compound will always have the same proportions or amount of each element by weight, no matter what the amount is, or source. For instance, a 50-gram sample of carbon monoxide will have 21.5 g of carbon and 28.5 g of oxygen.
