Answer: The average atomic mass of oxygen is 15.999 amu
Explanation:
Mass of isotope O-16 = 15.995 amu
% abundance of isotope O-16= 99.759 % =
Mass of isotope O-17 = 16.995 amu
% abundance of isotope O-17 = 0.037% =
Mass of isotope O-18 = 17.999 amu
% abundance of isotope O-18 = 0.204% =
Formula used for average atomic mass of an element :
Thus the average atomic mass of oxygen is 15.999 amu
