The percent abundances of two of the three isotopes of oxygen are 99.76% for16O, and 0.204% for18O. Use the atomic mass of oxygen given in the periodic table (see "Appendix H: Periodic Table of Elements") and the following data to determine the mass of17O, giving your answer to two significant figures:

15.994915 amu for16O

17.999160 amu for18O

mass of17O =amu

Answer rating: 100% (QA)

To determine the mass of 17O we can use the fact that the sum of the perc... View the full answer
