The analysis of a sample of Martian air collected by the Phoenix Lander shows that the ratio of oxygen and carbon dioxide isotopes present in the atmosphere of Mars is very similar to that of Earth. Due to Mars' low gravity and lack of magnetic field, lighter isotopes are lost to space and so an older atmosphere will consist of mainly heavier isotopes.
In other words the oxygen on Mars would consist mainly of O18 while on Earth our oxygen consist mainly of O16.
The atomic mass is an average, allowing for the relative abundances of different isotopes.
relative atomic mass
It's an average number allowing for the relative abundances of different isotopes.
All elements have an atomic mass relative to 12C having a mass of 12.
Chlorine (Cl) Atomic Number: 17 Relative Atomic Mass: 35.453
It allows for the relative abundances of different isotopes.
It allows for the relative abundances of different isotopes.
The atomic mass is an average, allowing for the relative abundances of different isotopes.
The relative atomic mass is the mean mass of the isotopes of an element. Since, by definition, these have different numbers of neutrons, their masses are different. This results in fractional values.
It's an average number allowing for the relative abundances of different isotopes.
The Atomic Mass number of an element is the sum of the protons and neutrons in the nucleus of an atom of that element.The relative atomic mass is the average atomic mass number of all the known isotopes of an element.

the relative atomic mass for the element potassium is 39.0983
Relative atomic mass, also called atomic weight, is listed on the periodic table for each element. There is no element listed on the periodic table with a relative atomic mass of 15.5.
It's an average number allowing for the relative abundances of different isotopes.
