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 isotope mass relative ) abundance 117Sn 116.90 59.9 124 S 12391 41.5 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.

Answer 1

Two isotope A with relative abundance xil.4.2 .. mais mi, ... b with relative abundance X2 (1) mass M2 Molar mass, n = Mixi + M₂ X2. 100 so, forsu M = 117859.7 124.41 .100 = 119.87 119.87 Angi so sn
