Question

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? i) More than 50% of all O atoms are 17O. ii) Almost all O atoms are 18O. iii) Almost all O atoms are 17O. iv) The isotopes all have the same abundance, i.e. 33.3%. v) The abundances of 17O and 18O are very small. Select one: a. iv b. iii c. v d. i e. ii
