A robot spacecraft returned samples from the planetesimal 98765 ALEKSlocated in the outer Solar SystemMass-spectroscopic analysis produced the following data on the isotopes of ruthenium in these samples mass relative isotope (amu) abundance 103.9 41.% 1019 these to complete the entry for ruthenium in the Periodic Table that would be used on 98765 ALEKSRound your entry for the atomic mass to 3 significant digits : 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
