Homework Help: Chemistry

Posted by Amy~ on Wednesday, August 25, 2010 at 7:25pm.

How would I solve this:

The atomic mass of 6/3Li and 7/3Li are 6.0151 amu and 7.0160 amu, respectively. Calculate the natural abundances of these 2 isotopes. The average atomic mass of Li is 6.941.

All I know is how to get the atomic mass and not the natural abundances.
