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.
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.
The atomic mass could be used to identify an element.
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.
The actual masses of atoms are very small and difficult to work with.
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?
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.
Two atoms are considered different isotopes of their element if they have different masses. This mass comes from the neutral-charged neutrons differing.
They have way different masses!!
All atoms are elements. Single (or even a "few") atoms do not have the properties of large masses of atoms.

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.
It's not better to do that for everyone, but it certainly is for chemists, since the electron structure of atoms is the building blocks for pretty much...everything they study. Nuclear physicists would surely rather arrange the elements based on atomic masses, for...something I'm sure. Fortunately, the Periodic Table of the Elements has them arranged both ways at the same time, whew!
the chemists goal is to understand the atoms that compose it
Chemists.
Yes, it is possible.
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.
the number of helium and hydrogen atoms is the same
Today we know that atoms can be destroyed to nuclear reactions but not by chemical reactions.
The products are very different.
