Tundance A robot spacecraft returned samples from the planetesimal 98765 ALEKS, located in the outer Solar System Mass spectroscopre analysis produced the following data on the isotopes of tin in these samples: Isotope mass relative (amu) abundance 116 Sn 115.90 91.3% 120 Su 119.90 8.75 Use these measurements to complete the entry for tin 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 ton in the Periodic Table we use here on Earth.
