Go to the site below, www.webelements.com, click on the element and scroll down the right hand side to "nuclear properties." Under that heading is isotopes. The abundance is given there.

How can i find the abundance of an isotope?

well i have two isotopes and i am given only one abundance for one. I need to find the other abundance for the other isotope to continue. Will that help me?
The relative abundances of all stable isotopes are given at the webelements link provided by DrBob . His example was for silver but you can connect from there to the other elements.
If you know there are ONLY two isotopes and you know the abundance of one of them, then the other one is 100% - percent of the one you have.
