It means that in any pure compound, the proportion of constituent elements (by mass) is a constant. This allows their chemical formulae to be determined.

What is meant by the law of constant composition for compounds?
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.
Does compound follow the law of constant composition?
because 789
Atoms of different elements combine in whole number what?
That is the law of constant composition.
Is the law of constant composition true for all types of compounds?
No, one example would be wüstite. Please see the link.
When did Dalton publish law of constant composition?
Joseph Proust, based on experiments conducted at the end of the 18th Century claimed that elements combined in constant proportions. Dalton's atomic theory, (1903) built on this earlier work and put it into a theoretic framework.

If Law of constant composition true for all types of compounds?
No,Law of constant composition is valid only for compounds made from the specified isotopes of the element.
Does compound follow the law of constant composition?
because 789
Why is the law of definite composition important?
Think of it in terms of a scientist performing a lab experiment. He/she will need to know the specific amounts of substance required to obtain the desired reaction. The law is fundamental for stoichiometry operations.
What are the drawbacks of law of constant composition?
kill kill king king
The first chemist to formally state the law of constant composition was?
Proust
Why law is important in chemistry?
This the law of mass conservation.
Atoms of different elements combine in whole number what?
That is the law of constant composition.
Is the law of conservation related to chemistry?
Yes, it is very important for chemistry.
Evidence that supports the law of constant composition?
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.
What would Proust say about the composition of all carbon dioxide molecules?
He would insist that all Carbon Dioxide molecules have the same composition, by his Law of Constant Composition.
The statement that a chemical compound always contains the same elements in exactly the same proportions is called the law of?
"In chemistry, the law of definite proportions and also the elements, sometimes called Proust's Law, states that a chemical compoundChemical_compoundalways contains exactly the same proportion of elementsChemical_elementby mass. An equivalent statement is the law of constant composition, which states that all samples of a given chemical compound have the same elemental composition." - Wikipedia
