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 tin in these samples: mass relative isotope (amu) | abundance 119 Sn 118.9 47.% 121.9 53.% 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 tin in the Periodic Table we use here on Earth. Sn
