WebLithium has two isotopes, 6 Li and 7 Li, with masses of 6 amu and 7 amu respectively. If Lithium has an atomic weight of 6.94 amu, we can determine the abundance of each isotope. First, we define one. of the abundances as x. In this case, the abundance of 6 Li will be x. This means that the abundance of 7 Li= 1-x. Using what we learned above ... WebLithium has two naturally occurring isotopes: 6 (Li) Lithium has a mass of 6.015 and is 7.42% abundant; 7 (Li) Lithium has a mass of 7.016 and is 92.58% abundant. Calculate the atomic mass of lithium. 6.015 multiplied by 0.0742 + 7.016 multiplied by 0.9258 = 6.94.
