The weighted average mass of oxygen, commonly represented as the atomic weight of oxygen, is approximately 16.00 Atomic Mass units (amu). This value accounts for the natural abundance of its isotopes, primarily oxygen-16, oxygen-17, and oxygen-18. The majority of oxygen found in nature is oxygen-16, which is why it has the most significant influence on the average.

What is the average atomic mass compared to atomic mass?
The average atomic mass is a weighted average of the masses of all isotopes of an element, taking into account their abundance. The atomic mass listed on the periodic table is the weighted average of all naturally occurring isotopes of the element. So, they are essentially the same thing, with the average atomic mass being a more specific term.
What is the weighted average atomic mass of bromine?
The weighted average atomic mass of bromine is approximately 79.904 u. This value is calculated based on the natural abundance of bromine's isotopes.
What is the atomic number for oxygen 15.9994?
The atomic number for any isotope or mixture of isotopes of oxygen is 8.
What is the difference between mass number relative atomic mass and average atomic mass?
The mass number is the total number of protons and neutrons in an atom's nucleus. Relative atomic mass is the weighted average mass of all the isotopes of an element, taking into account their natural abundance. Average atomic mass is the weighted average mass of an element's isotopes in a given sample, considering their abundance in that sample.
Weighted average mass of the mixture of its isotopes?
The weighted average mass of a mixture of isotopes is calculated by multiplying the mass of each isotope by its natural abundance, and then summing these values together. This gives a more accurate representation of the overall mass of the isotopes in the mixture, taking into account their relative abundances.

What is center of the mass?
It is basically the "average location" of all the masses. A sort of weighted average, actually.

Is an average mass of the different isotopes of the element?
The average atomic mass of an element is the weighted average of the masses of its isotopes, based on their abundance in nature. It is calculated by multiplying the mass of each isotope by its relative abundance, then summing these values together. This average mass is given on the periodic table.
Why do elements which exists as isotopes have fractional atomic mass?
Each isotope of an element has a different Atomic Mass, so an average is taken of all the isotopes, but the average is weighted because the natural abundance (%) of each isotope is factored in. If hydrogen-1 is much more abundant than deuterium and tritium, then the weighted average will be closer to 1 than 2 or 3 but not a whole number. The following equation shows how percent abundance factors into the weighted average. (atomic mass A)(X% abundance) + (atomic mass B)(Y% abundance)...=(weighted average of all isotopes of the element)(100% abundance)
Which best describes the definition for the atomic mass of an element?
The atomic mass of an element is the average mass of an element's isotopes, weighted by their natural abundance. It is expressed in atomic mass units (u) and is often close to the mass number of the most abundant isotope of the element.
