Average atomic mass is calculated for those elements which exists in two or more than two isotopic forms. The natural abundances of different isotopes of an element are different and hence they are the deciding factors in determination of ...
What is the average atomic mass of Mg?Atomic Mass and Mass Number:The atomic mass is a form of calculated average mass for all the atoms of an element. This differs from mass numbers in that a mass number refers to the mass of a specific atom or the atoms of an isotope of an ...
Let the percentage of X-16 isotope =x The percentage of X-18 isotope =(100-x) From the information the average atoic mass of the element X is = (x xx16)/(100)+((100-x)xx18)/(100) But the given atomic mass of the element X=16.2 u (x xx16)/(100)+((
The average atomic mass of oxygen is 15.999 AMU. This value rounds to 16, which indicates that oxygen-16 is the most abundant isotope of oxygen... Learn more about this topic: Average Atomic Mass | Definition, Formula & Calculation from...
