A robot spacecraft returned samples from the planetesimal 98765 ALEK , located in the outer Solar System. Mass- spectroscopic analysis produced the following data on the isotopes of molybdenum in these samples: isotope (amu) abundance mass relative {}^100Mo 99.9 91.8% 95 Mo 94.9 8.2% 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 necessarily the same numbers as the entry for molybdenum in the Periodic Table we use here on Earth.

<p> To determine the average atomic mass of molybdenum based on the given isotopic masses and their relative abundances, we use the formula: <br />\[ \text{Average atomic mass} = \sum (\text{isotope mass} \times \text{relative abundance}) \]<br />Given the isotopes \( ^{100}Mo \) and \( ^{95}Mo \) with masses 99.9 amu and 94.9 amu, and relative abundances 91.8% and 8.2% respectively, we plug these values into the formula to get:<br />\[ \text{Average atomic mass} = (99.9 \times 0.918) + (94.9 \times 0.082) = 99.49 \text{ amu} \]<br />Rounding to three significant digits, the average atomic mass is \( 99.5 \) amu. This would be the entry for molybdenum in the Periodic Table on 98765 ALEKS.</p>
