Isotope Calculations

There are four variables in a typical isotope mass/abundance problem involving two isotopes of an element (A and B).
  1. Mass of Isotope A
  2. Mass of Isotope B
  3. Percent Abundance of Isotope A
  4. Average Mass of Element

You may choose a problem to determine any of these. You will be given three of the inputs, and be asked to solve for the missing piece of information.

Which type of problem would you like to solve?

Determine Mass of Isotope A
Determine Mass of Isotope B
Determine Percent Abundance of Isotope A
Determine Average Mass of Element
