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: relative mass isotope (amu) abundance 101 Ru 100.9 90.9% 102 Ru 101.9 9.1% 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 4 significant digits.

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:
mass
relative
isotope
(amu) abundance
101 Ru
100.9
90.9%
102.
Ru
101.9
9.1%
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 4 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.
