🤓 Based on our data, we think this question is relevant for Professor Montag's class at COD.
We’re being asked to identify the element given the mass of its naturally occurring isotopes.
We can use the following equation:
where atomic mass = average atomic mass of the element and f.a. = fractional abundance of the isotope.
To get f.a., we simply need to divide the given percent abundance by 100.
An element has two naturally occurring isotopes. Isotope 1 has a mass of 120.9038 amu and a relative abundance of 57.4%, and isotope 2 has a mass of 122.9042 amu.
By comparison to the periodic table, identify this element.
