Mercury's atomic mass is 200.59, but we can round that to 201 (this is known as the mass number). This is a tally of the total number of particles in an atom's nucleus, so an 'average' atom of mercury contains 201 particles in its nucleus. arya latest tamil movieWebCalculating atomic mass with average atomic mass formula: Step 1: (%Abundance / 100) x (atomic mass of each isotope) $$ 0.7578 * 34.96885 = 26.50 $$ $$ 0.2422 * 36.96590 = 8.95 $$ Now, determine the value of a given sample quality: $$ 8.95 + 26.50 = 35.45 $$ Use our atomic weight calculator for quickly calculating the atomic weight of an element. bangka masuk provinsiWebJan 30, 2016 · Explanation: You will have to look up the isotopic distribution of lithium nuclei. ALL lithium nuclei have 3 positively charged nuclear particles, protons, i.e. Z = 3. These 3 particles give rise to the element's identity. If you take the weighted average of ALL lithium nuclei, we get an average mass of 6.941 g ⋅ mol−1.
