This is atomic mass number of 98 which is distinct from an atomic mass in that it is a count of nucleons in the nucleus of one isotope and is not an actual mass of an average sample (with a natural collection of isotopes) relative to 12C. The 98Tc isotope has a mass of 97.907214. For elements that are not stable enough to persist from the creation of the Earth, the convention is to report the atomic mass number of the most stable isotope in place of the naturally occurring atomic-mass average.
