Homework Help: Chemistry

Posted by Liz on Monday, September 8, 2008 at 8:55pm.

I am supposed to find the percent abundancies of two isotopes. I am given the masses of both isotopes, along with the atomic mass. (This is a fictional element with only those two isotopes.) I am not given percentages for either isotope... how do I solve this?
