A robot spacecraft returned samples from the planetesimal 98765 ALEKS, Ilocated in the outer Solar System. Mass-spectroscoplc analysis produced the followlng data on the Isotopes of ruthenlum In these samples: mass relative isotope (amu) abundance 100 Ru 99.90 58.% 96 Ru 95.91 42.% Use these measurements to complete the entry for ruthenium in the Periodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 2 significant digits. Caution: your correct answer will have the same format but not necessarily the same numbers as the entry for ruthenium in the Periodic Table we use here on Earth.
