2)A robot spacecraft returned 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: isotope 100 Ru 104 Ru mass (amu) 99.9 103.9 relative abundance 60.% 40.% 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 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.

Transcribed Image Text:2)A robot spacecraft returned 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:
isotope
100 Ru
104 Ru
mass (amu)
99.9
103.9
relative abundance
60.%
40.%
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 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.
