WebLithium has two naturally occurring isotopes. Li-6 has atomic mass of 6.015 amu and Li-7 has atomic mass of 7.016 amu. If the atomic mass of lithium is 6.941 amu, what are the percent abundances of Li-6 and Li-7? To do this problem, you will need to use a system of equations. (Additional hint to do this problem, you need to use a number that I ... Webatomic weight, also called relative atomic mass, ratio of the average mass of a chemical element’s atoms to some standard.
