- 1. Using a deuteron beam, a sample of isotopically enriched fluorine is generated, consisting of 18F and 19F. Because this is not a natural sample, the average atomic mass on the periodic table cannot be used! Given the following abundances in the sample, calculate the new atomic mass (in amu) of the fluorine in the sample. Do not include units in your answer. Show work and upload that work to the final question of this quiz. 18F: 18.01 amu, 71.79% 19F: 19.008 amu, 28.21% 2.
