The law of constant composition applies to chemical compounds, stating that a compound is always made up of the same elements in the same proportion by mass. This means that the ratio of elements in a compound is fixed and does not change regardless of the source or method of preparation.
One drawback of the law of constant composition is that it may not hold true for all substances, especially those with variable composition such as alloys or solid solutions. Additionally, it assumes that compounds are made up of discrete units, which may not always be the case at the molecular level. Finally, the law does not account for isotopic variations in elements.
The scientist who helped prepare the way for Dalton's work by developing the law of constant composition was Joseph Proust. Proust formulated this law, also known as the law of definite proportions, which states that a given compound always has the same elements in the same proportion by mass.
The law of constant composition states that a compound will always have the same proportion of elements by mass regardless of its source. This means that hydrate salts, which contain a specific number of water molecules attached to the salt crystal, will have a consistent ratio of water to salt molecules regardless of how they are produced or obtained.
Ohm's Law holds true only at a constant temperature because it assumes a linear relationship between voltage, current, and resistance, which is only valid when temperature remains constant. Changes in temperature can alter the resistance of a material, leading to deviations from Ohm's Law.
The law you are referring to is the Law of Definite Proportions. This law states that a chemical compound always contains the same elements in the same proportions by mass, regardless of the source of the compound.
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.

The law of constant proportion, also known as the law of definite proportions, states that a chemical compound always contains its component elements in fixed ratio by mass. In seawater, this law applies to the dissolved salts, primarily sodium chloride, which consistently makes up about 3.5% of seawater by mass. Regardless of where seawater is sampled, the proportion of these dissolved salts remains relatively constant, demonstrating that the chemical composition of seawater is uniform despite variations in other components. This consistency is crucial for marine life and oceanic processes.
That is the law of constant composition.
Boyle's law applies to pressures and volumes at constant temperature P1V1 = P2V2. Charles' Law applies to volume and temperature at constant pressure V1/T1 = V2/T2. With temperatures in Kelvin the relationship between temperature and volume is directly proportional.
The law of constant composition for compounds is a law in chemistry according to which any given compound always contains the same component elements in the same ratios, by mass. The ratios do not depend on where the compound comes from or the way in which it was produced.
A piece of evidence that is commonly used to prove the law of constant composition is that any sample of water is 88. 71 percent oxygen and 11. 19 percent hydrogen. It was formulated by Joseph Proust.
Joseph Louis Proust (1754-1826), In 1799 Proust stated that "Compounds always contain the same elements in a constant proportion by mass." This statement is now called law of definite composition or the law of constant proportion.

In water, there is always 8 times the mass of oxygen than there is of hydrogen.
