Arobot 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:
isotope
e mass relative
(amu) abundance
112 sn 111.9
93.5%
116 sn 115.9 6.5%
use these measurements to complete the entry for tin in the periodic table that would be used on 98765 aleks. be sure your answers have the correct number
of 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
