because atoms from each element is different. relative masses of atoms is like their identity. it gives information on their weight, their density, their number of subatomic particles(protons and neutrons) and etc, etc.

most importantly, relative masses of atoms allows chemist worldwide to accurately communicate with each other the amount as well as the composition of compound used in their reactions.

Why do chemists use relative masses of atoms compared to a reference isotope rather than absolute masses in their calculations?

Chemists use relative masses of atoms compared to a reference isotope because it allows for easier comparison and calculation of chemical reactions. Absolute masses can vary, but relative masses provide a consistent point of reference for analysis.


Why do chemists use relative mass of atoms compared to a reference isotope rather than the actual masses of the atoms?

i need a answer goish just tell me Edit :: This looks suspiciously like a homework question. It wouln't be called the "Average Atomic Mass" if it wasn't the average of all the isotopes, now wouldn' it?


What is the relative formula mass of copper?

The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.


Who was The first attempt at publishing a list of relative atomic masses?

John Dalton tried to work out the relative masses of atoms; but his calculations were wrong, although the principle was correct. He was, however, the first to establish a table of atomic masses with hydrogen, the lightest atom, as the standard.


What is the sum if the masses of the atoms present in the formula of an ionic compound?

The sum of the masses of the atoms in an ionic compound is equal to the formula mass of the compound. It is calculated by adding the atomic masses of all the atoms present in the formula unit.

Why do chemist use relative masses of atoms compared to a reference isotope rather than the actual masses of atoms?

because, the mass of an atom is too small to be easily used as a point of reference. Comparing it to the C-12 atom (so relative Atomic Mass) is much easier. I think this is the answer.


What are the relative formula masses of hydrogen molecules?

The relative formula mass of a hydrogen molecule (H2) is calculated by adding the atomic masses of the two hydrogen atoms. Each hydrogen atom has an atomic mass of approximately 1, so the relative formula mass of a hydrogen molecule is 2.


What is the relative atomic mass of hydrogen peroxide?

The relative atomic mass of hydrogen peroxide, H2O2, is approximately 34.01 g/mol. This value is calculated by adding the atomic masses of the elements in the molecule (2 hydrogen atoms and 2 oxygen atoms).


Why chemists must work in the macroscopic world to find out about the submicroscopic atom?

the chemists goal is to understand the atoms that compose it


How do you calculate Mr?

To calculate the relative molecular mass (Mr) of a molecule, add up the atomic masses of all the atoms in the molecule as shown in its molecular formula. For example, the Mr of H2O (water) is calculated by adding the atomic masses of 2 hydrogen atoms and 1 oxygen atom.

Do chemists count atoms by weighing matter?

Yes, it is possible.


What kind of scientists studies elements atoms and molecules?

Chemists.


Why is the mass numbers of isotopes exact whole numbers but the relative masses of most Atoms are not exact whole numbers?

Relative atomic massisthe ratio of the averagemassofatomsof anelementto 1/12 of the mass of an atom ofcarbon-12. The mass number of an isotope is the sum of protons and neutrons in the atoms of the isotope.
