Problem: Germanium has five naturally occurring isotopes: 70 Ge, 20.5%, 69.924 amu; 72 Ge, 27.4%, 71.922 amu; 73 Ge, 7.8%, 72.923 amu; 74 Ge, 36.5%, 73.921 amu; and 76 Ge, 7.8%, 75.921 amu.What is the atomic weight of germanium?
FREE Expert Solution
We’re being asked to calculate the atomic weight of germanium
We can use the following equation:
where:
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.
