The atomic weight (not mass) of a chemical element is calculated considering the isotopic composition of the element and the atomic masses (not weights) of these isotopes.
the elements in the substance are mixtures of their isotopes
The two main factors in determining the average atomic mass of an element are:the isotopic composition of the element (the fraction of each isotope)the atomic mass of each isotope
The average atomic mass of an element is closest to the mass number of the most abundant isotope of that element. This is because the average atomic mass takes into account the relative abundance of each isotope when calculating the overall mass.
To calculate the average atomic mass of an element, you need to multiply the mass of each isotope by its abundance (as a decimal), then sum these values for all isotopes of that element. This will give you the weighted average atomic mass. The formula is: average atomic mass = (mass isotope 1 x abundance 1) + (mass isotope 2 x abundance 2) + ...
average atomic massof an element=(Atomic mass of first isotope X % of that isotope) + (Atomic mass of second isotope X % of the second isotope)
Isotopes - that same element with a different atomic weight.
The atomic mass of an element is determined by calculating the weighted average of the masses of its isotopes, taking into account their relative abundance.
the elements in the substance are mixtures of their isotopes
The weighted average of the atomic masses of an element's naturally occurring isotopes is called the atomic mass. This value takes into account the abundance of each isotope in nature when calculating the overall average atomic mass of the element.

The atomic weight of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This information is typically found on the periodic table of elements.

The relative atomic mass of an element can be determined by calculating the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is usually expressed in atomic mass units (amu) and can be found on the periodic table.
the Atomic Mass in g/ml is the molar mass of the element
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
The given mass of an element on the periodic table is determined by calculating the weighted average of all naturally occurring isotopes of that element. If the element does not occur in nature, the atomic mass of the most stable isotope is given.
