Question
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
115.
Sn
114.90
50.%
114
Sn
113.90
50.%
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.
