How can the existence of atoms help to explain the law of definite proportions?

If the mass proportions of the original substances do not equal these definite proportions, there will something of one of the original substances be left over. Note that this is special, it could as well have turned out to be possible for substances to combine in any proportion. So we find the law of definite proportions. Now we should be baffled and wonder how on Earth could that be so? And then we could think of substances being made of small particles (atoms) or groups of such particles (molecules) to explain the laws of nature that we found. So the laws of definite proportions and multiple proportions are (partially) proof for the existence of atoms which combine into molecules. The laws are the real thing and atoms and molecules and their chemical formulas are the ideas we make to understand the laws.

The existence of atoms explains the law of definite proportions by suggesting that chemical substances are made up of atoms that combine in fixed ratios. Each atom has a specific mass and combining these atoms in fixed proportions leads to compounds with consistent ratios of elements. This consistency supports the law of definite proportions, which states that a compound will always contain the same elements in the same ratio by mass.

What laws provided evidence for the existence of atoms?
The law of definite proportions, the law of conservation of mass, and the law of multiple proportions all provide evidence for the existence of atoms.
What are two or more different atoms are combined in definite proportions in any?
compound
What is the ratio of elements in a compound?
The stoichiometry is governed by the laws of definite proportions and multiple proportions.
Is a compound a chemical combination of atoms whose proportions do not vary?
No. A compound is a mixture of different elements. They can be in different proportions. Examples are CH3 and CH4.
What formula represents the actual number of atoms of each element in a compound?
A formula that gives the ratio of elements in a compound is called an empirical formula. On the other hand, the formula that shows the number of atoms in each element present in a molecule is called a molecular formula.

The law of definite proportions, the law of conservation of mass, and the law of multiple proportions all provide evidence for the existence of atoms.

How did Jeremias Benjamin Richter apply the principles of stoichiometry?
Jeremias Benjamin Richter was the first to develop titration and the law of definite proportions. This law proved the existence of atoms.
How are compounds diffident from mixtures?
Compounds are composed of atoms of different elements chemically bonded in definite proportions. The components of mixtures are not chemically combined and they do not have definite proportions.
The ratio in which atoms are blended together in compounds is shown by an?
By the law of definite proportions.
What are two or more different atoms are combined in definite proportions in any?
compound
Is ratio of atoms is always the same in a compound?
Generally yes (the law of definite proportions); as exceptions - nonstoichiometric compounds.
What edvidence convinced Dalton that elements must be made of individual particles called atoms?
He deduced that from the law of definite proportions.
What law does this statement agree with If it doesn't have exactly have one oxygen atom and two hydrogen atoms its not water?
the law of definite proportions
What is the ratio of elements in a compound?
The stoichiometry is governed by the laws of definite proportions and multiple proportions.
Do atoms have definite volume?
Yes, atoms have a definite volume.
What is the experiment that john Dalton carried out that led to the law of definite proportions?
John Dalton wrote four essays called "Experimental Essays" based on his "Atomic Theory", which explained matter as consisting of discrete atoms, that there was one type of atom for each element, and that the compounds were made of combinations of different types of atoms in fixed proportions.
