A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar 5y stem. Mass-spectroscopic analysis produced the following data on the isotopes of ruthenlum in these samples: Use these measurements to complete the entry for ruthenium in the Penodic Table that would be used on 98765 ALEKS. Round your entry for the atomic mass to 3 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
