Answer:
The average atomic mass os isotopes of oxygen is 16.997603
Explanation:
The average of the atomic mass of the three isotopes of oxygen is16.997603.
process:
the atomic mass of the oxygen isotopes are given in the question and its natural abundance.
We need to find the relative atomic mass of oxygen isotope.
Adding the atomic masses of the oxygen isotopes and dividing it with 3 to find the relative atomic mass.

average atomic mass =
99.761 × 15.99 + 0.039 × 6.999 + 0.200 × 17.999160 u / 100
hence, ur ans is
= 15.9994 u
