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.

MaxineChemists use relative comparisons of masses of atoms because comparing the masses of atoms provides a standard way to quantify differences in the weights of different elements. By using atomic masses relative to a standard reference point (usually carbon-12 or oxygen-16), chemists can easily make comparisons and calculations in chemical reactions and formulas.
It is important to know the relative masses of atoms since this is what will serve as their identity. This will give you all the necessary information like elements present, weight and density among others.
Because the actual masses of atoms are WAY to small and VERY difficult to work with!
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.
Elements have isotopes with different mass numbers for same element.The average isotopic masses gives atomic mass of the element as a whole.hencethe term average atomic mass.

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?
Chemists use the relative mass of atoms because it allows for easier comparison between different elements. By choosing a reference isotope, such as carbon-12, they can assign a standardized value for comparison. This makes calculations and measurements more convenient in chemical reactions and analysis.
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?
The first attempt at publishing a list of relative atomic masses was by John Dalton in the early 19th century. Dalton proposed a system of chemical symbols and atomic weights based on the hydrogen atom as a 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.

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).
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.
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

Do chemists count atoms by weighing matter?
Yes, it is possible.
What kind of scientists studies elements atoms and molecules?
Chemists.
Why is the atomic mass scale also called the relative atomic mass scale?
The atomic mass scale is sometimes referred to as the relative atomic mass scale because it is a scale that compares the mass of atoms of different elements to the mass of a carbon-12 atom, which is assigned a mass of exactly 12 atomic mass units. By comparing the masses of atoms relative to carbon-12, scientists can determine the relative masses of different elements.
