The element oxygen consists of three naturally occurring isotopes: 16O, 17O, and 18O. The atomic mass of oxygen is 16.0 amu. What can be implied about the relative abundances of these isotopes? More than 50% of all O atoms are 17O. Almost all atoms are 18O. Almost all O atoms are 17O. The isotopes all have the same abundance, i.e. 33.3%. The abundances of 17O and 18O are very small.

3. Calculate the atomic mass of oxygen if the three common isotopes of oxygen have masses of 15.995 amu (99.759% abundance), 16.995 amu (0.037 % abundance), and 17.999 amu (0.204 % abundance).
