Asked by Robert

An element has three stable isotopes. One has a mass number of 63 and an abundance of 50%. The second has a mass number of 65 and an abundance of 30%. The third has a mass number of 67 and an abundance of 20%. Calculate the relative atomic mass of this element.

I am so confused at this question! Could someone help?
Answered by DrBob222
The atomic mass of an element is the weighted average of the mass of all of the isotopes.
63(0.5) + 65(0.3) + 67(0.2) = ?
