The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an Atomic Mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.

How do you find relative atomic mas?
Relative atomic mass is determined by comparing the mass of an atom to one-twelfth of the mass of a carbon-12 atom, which is defined as exactly 12 atomic mass units (amu). To find it, you can use a mass spectrometer to measure the isotopic masses and their relative abundances, then calculate a weighted average based on these values. The formula used is: relative atomic mass = (isotopic mass × relative abundance) / total relative abundance for all isotopes. This gives a value that reflects the average mass of an atom of an element as found in nature.
Why is the atomic mass scale also called the relative atomic mass scale?
All atomic masses are determined by comparing them to the mass of an atom of carbon12. One atomic mass unit equals one twelfth the mass of an atom of carbon12. That's why its called relativeatomic mass.
How relative atomic mass of an atom can be determined?
The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø
What are the relative atomic mass of subatomic particles in atom?
The relative atomic mass of electrons is considered negligible, as they are much lighter than protons and neutrons. Protons and neutrons each have a relative atomic mass of approximately 1, as they are found in the nucleus of an atom and contribute to its overall mass.
Do subscripts represent the relative mass of each type of atom in the compound?
No, subscripts in a chemical formula represent the number of atoms of each element in the compound. The relative mass of each atom is accounted for by the atomic mass of the element found in the periodic table. So, atomic mass, not subscripts, gives you the relative mass of each type of atom in a compound.

What does the atomic mass of an atom represent?
the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
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.
Why is the atomic mass of an atom the average atomic mass?
It allows for the relative abundances of different isotopes.
What is the difference between relative isotopic mass and relative atomic mass?
Atomic Mass is the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.Relative isotopic mass is the mass of an atom of an isotope of an element compared with one-twelfth the mass of an atom of carbon-12.Thus an element will have ONE Relative Atomic Mass but there may be MANY individual Relative Isotopic Masses for an Element (depending on how many Isotopes it has).
What is an atomis mass?
Atomic mass is the mass of an atom, typically expressed in atomic mass units (amu). It is a weighted average of the mass of an atom's isotopes, taking into account their relative abundance in nature. It is usually found on the periodic table beneath the chemical symbol of each element.
Atomic mass of an element?
The atomic mass of an element is the relative mass of its atom as compared with the mass of a carbon-12 atom taken as 12 units.
Why is the relative atomic mass of an atom in a fraction?
It's an average number allowing for the relative abundances of different isotopes.
What is the number of atomic mass in an atom?
Relative mass number of an electron is 0
