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 molybdenum in these samples: mass relative isotope (amu) abundance 92 Mo 91.91 90.4% 98 Mo 9.6% 97.91 Use these measurements to complete the entry for molybdenum 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 molybdenum in the Periodic Table we use here on Earth.

thank youu! <3
Transcribed Image Text: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 molybdenum in these samples:
mass
relative
isotope
(amu) abundance
92 Mo 91.91
90.4%
98 Mo
9.6%
97.91
Use these measurements to complete the entry for molybdenum 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 molybdenum in the Periodic Table we use here
on Earth.
