What is a factor in determining the average atomic mass of an element

The factor in determining the average atomic mass of an element is: B or 2 relative abundance of each isotope because the by looking at how many protons , electrons and neutrons the most isotope is of the element has relative abundance.

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6

well, you would divide 135 by 33 to get your answer. then that is how many seconds it would take. boardman should fly about 132 m or 4.090909090909091 seconds.
