For the following questions determine the percent abundance of each isotope. The periodic table is NOT needed for these questions and may even confuse you. Ideally you would use the algebra method shown in the course but if you find that confusing you can memorize the following formulas instead. % of smaller isotope mass larger isotope average mass mass larger isotope-mass smaller isotope x100% % of larger isotope = 100% - % of smaller isotope a) Oxygen - 16 and Oxygen 18 with an average atomic mass of 16.2 18-16.2 * 100%- 110 Of 18-16 b) An element has two isotopes "X and $4X, with mass numbers of 52.0 and 54.0 respectively. The relative atomic mass is 53.5.

Finding atomic mass from isotope mass and natural abundance 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 119 S Sn 118 Sn Sn mass relative (amu) abundance 118.9 93.3% Explanation 117.9 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. 6.7% X Check 3 ? O ol Ar ve Graw Hill LLC.
