How is atomic mass calculated
WebCalculating 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. WebCalculate the mass defect of a 63 Cu nucleus if the actual mass of 63 Cu in its nuclear ground state is 62.91367 u. 63 Cu nucleus has 29 protons and also has (63 – 29) 34 neutrons.. The mass of a proton is 1.00728 u and a neutron is 1.00867 u. The combined mass is: 29 protons x (1.00728 u/proton) + 34 neutrons x (1.00867 u/neutron) = 63.50590 u
