WebThe table below shows the exact mass of each isotope (isotopic mass) and the percent abundance (sometimes called fractional abundance) for the primary isotopes of Carbon. Average Atomic Mass = (12.0000) (.9890) + (13.0033) (0.0110) = 12.011 amu. The answer, 12.011 amu, is the same value found for Carbon on the periodic table. 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.
