Average atomic mass4/20/2023 Therefore the atomic mass of germanium is 72.71 amu. The average atomic mass of an element is the. The atomic mass of an element is the average relative mass of its atoms as. The average atomic mass of an element can be calculated using the following formula: 'Ratio of isotope (atomic mass of isotope) + ratio of 2nd isotope (atomic mass of isotope) + any. As a result, while calculating an elements atomic mass, the isotopic mixing must be taken into consideration. Calculate the atomic mass of germanium.ġ) First you would take the different percent's of Germanium and multiple that with the different isotopes then divide it all by 100.Ī.A.M = (Ge-70) (20.5%) (Ge-72) (27.4%) (Ge-73) (7.8%) (Ge-74) (36.5%) (Ge-76) (7.8%) Periodic Table With Atomic Mass Alkali Metal Alkaline Earth Transition Metal. Germanium has the following isotopic composition. When calculating average atomic mass you have to use this formula.Ī.A.M = (mass isotope A) (%A) (mass isotope B) (%B). Isotopic abundance is the relative amount of each isotope present in a natural sample of an element, expressed as a percent.Ĭl has 2 isot opes: 25% are Cl-37 and 75% are Cl-35 The average atomic mass (mass on the periodic table) is a weighted average of all isotopes. A.m,u.'s are a measure defined by C-12, meaning that one a.m.u is exactly 1/12th the mass of a C-12 atom. Average Atomic Mass isotopic abundance of that particular isotope. The average atomic mass is the mass of an atom which is expressed in atomic mass units (a.m.u).
