How do you calculate average atomic mass
WebAnd the whole point of an average atomic mass to determine how much mass there would be in a pure sample of a single element. If I use your example and assign random abundances to the numbers, say 90% for 6, 9% for 5, and 1% for 3; we can see the differences in using arithmetic compared to a weighted average. WebThe average atomic mass (sometimes called atomic weight) of an element is the weighted average mass of the atoms in a naturally occurring sample of the element. Average …
