Ok...Chem 1 honors stuff here...So we are doing half lives and crap like that. Well I need to find the average of the first five on my graph. And I dunno how to do that. How do I do it?

First you locate the half lives of each one. Then you take the mean average of them. *Adding them all up and dividing by the total amount (5).

The easiest way is to find a copy of the CRC Handbook of Chemistry and Physics. Your library should have one. I'm sure you can also Google a bit and find the same information.
The half-life of Al-28 is 2.31 minutes.
I'm not sure what you're needing to find the average of...Al-28 has only one half-life...
