A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System. Mass-spectroscopic analysis produced the folowing data on the isotopes of molybdenum in these samples: relative mass Isotope amu abundance 92 Mo 91.91 98.8% 97 Mo 96.91 1.2% 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 necessanily the same numbers as the entry for melybdenum in the Periodic Table we use here on Earth.
