i have already submitted this problem once but it was not fully answered. i need the atomic mass AND the atomic number. PLEASE ANSWER ASAP

A robot spacecraft retumed samples from the planetesimal 98765 ALEKS, located in the outer Solar System, Mass-spectroscopic analysis produced the following data on the isotopes of ruthenium in these samples: Use these measurements to complete the entry for ruthenlum in the Perlodic 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 fable we use here on Earthly
