Lithium-7 mass
WebDetermine the atomic mass of lithium, given the isotopiccomposition: 92.4% lithium-7 (mass 7.016 u) and 7.60% lithium-6 (mass 6.015 u).1 Answer: I don't know what's the answer 8. 1. What is the average atomic mass of Ca? What is the molar mass of Ca? 2. The atomic mass of Br is 79.90 amu. What is its molar mass? 3. WebThe relative mass difference between the two isotopes of lithium is about 16%, which is among the highest of thermally ionized elements. Isotopic fractionation during mass spectrometric and other instrumental analyses is severe and, in the absence of a third isotope, the effect of mass discrimination cannot be internally corrected.
