Please help. Suppose that a newly discovered element called Centium has three isotopes that occur in nature. These are Centium-200, 203, and 209. Assume that these isotopes occur in equal amounts in nature. What will be the average atomic mass of this element?

This isn't a CS question, (seems more like chemistry) but I'll still try to answer it :-P

Since all three isotopes are distributed equally in nature, all you have to do to compute the average atomic mass for the element is to sum up the masses of their different isotopes and divide them by three.
