The Atomic Mass is the total mass of all the sub atomic particles (i.e. the mass of the whole atom): Electrons, Neutrons and Protons.
Therefore, it identifies isotopes (as they have different number of sub atomic particales - even for the same element) and thus total mass differs.
There can be a fair amount of difference between the Atomic Mass of the most common isotope of an element and its Atomic Weight - which is averaged (weighted average). This makes a difference for single atom calculations, but makes little real difference in bulk calculations.
The Atomic Mass of an element represents the average mass of an atom of that element, taking into account all its isotopes and their natural abundance. It gives an idea of how heavy the atom is compared to a standard unit, usually carbon-12.
The atomic mass of an element tells you the average mass of an atom in the element.
It tells the sum of number of protons and neutrons in an atom and how many grams a moled of that type of atom would weigh.
The mass number determines how many nucleons (protons and neutrons) an atom has.
equals the number of protons and neutrons

Do you need atomic number to find atomic mass?
No, you do not need the atomic number to find the atomic mass of an element. The atomic mass is the weighted average of the masses of the isotopes of an element, whereas the atomic number is the number of protons in the nucleus.
What is the atomic mass for magnesiam?
The atomic mass of magnesium is approximately 24.305 amu (atomic mass units).
Which element has a greater atomic mass A or B?
Element A has a greater atomic mass than element B if the atomic mass value of A is higher. The atomic mass represents the average mass of an element’s isotopes based on their abundance in nature.
