What is atomic weight of oxygen?

15.999 u
Oxygen/Atomic mass
Another example: oxygen exists as a mixture that is 99.759% 16O, 0.037% 17O and 0.204% 18O. The atomic mass of oxygen (use percent natural abundance data from Table 2.5.1) would be calculated as follows: Atomic mass = (%1)(mass 1) + (%2)(mass 2) + (%3)(mass 3) 0.99759(15.995u)+0.00037(16.995u)+0.00204(17.999u)=15.999u.
