The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
Oxygen is a non meta element. Atomic mass of it is 16.
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
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
relative atomic mass
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.
The relative atomic mass is 83.798. So where did you get that it is not determined.
Oxygen is a non meta element. Atomic mass of it is 16.
The atomic weight (not mass) of oxygen is [15,99903; 15,99977] or in an abridged form 15,999. The term atomic mass is used only for isotopes. The mass number is the sum of neutrons and protons in an atomic nucleus.
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 unit for atomic mass is 1/12 from the mass of the isotope 12C.
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
The atomic mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
The relative atomic mass of sulfur is 32.06 g/mol and the relative atomic mass of oxygen is 16.00 g/mol. Therefore, the relative molecular mass of SO2 (sulfur dioxide) is 32.06 + (16.00 x 2) = 64.06 g/mol.

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.
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.
