Oh, actually, I got it now; as I said in my intro, I took a chemistry class nearly 20 years ago, not just last semester, as with most of the cases on this website; I'm just trying to get refreshed and get through these textbooks in consideration for prep for graduate school and the subject...

What specifically about weighted average? Right now, there isn't enough information to do a weighted average; weighted average is usually associated with finding atomic masses; however, this question is before or after that, depending on Dalton's formulations.

To get the weighted average, you'd need to know the total mass or the mass in the isotopes most abundant state; however, the question is actually asking for the total mass, so, it doesn't appear as if enough information has been provided.

That's true, but, I'm still stuck; the weighted average only helps you determine the atomic mass; can you be more specific with say, an equation might use?

Yes, but, I'm still stuck; how do I begin?

Seemingly, the drawing does not offer much more information, but, I'll describe the drawing for you; X-23 is represented by gold balls and there are 5 of these gold balls; X-25 is represented by green balls and are 15 of these green balls; textbook is by Darrell, Ninth Edition

I believe that this question may be solved by the John Dalton ratios, but, I'm confused: While traveling to a distant universe, you discover the hypothetical element “X.”You obtain a representative sample of the element and discover that it is made up of two isotopes,X-23 and X-25. To help your...
