We’re being asked to identify the element using the abundances and masses of its isotopes.
We can use the following equation to calculate the atomic mass:
atomic mass = average atomic mass of the element
f.a. = fractional abundance of the isotope.
To get f.a., we simply need to divide the given percent abundance by 100.
We’re given the following values:
An element “X” has five major isotopes, which are listed below along with their abundances. What is the element?
