MaxineThe average Atomic Mass of copper is 63.55 g/mol. This value is calculated by taking a weighted average of the masses of copper-63 and copper-65, based on their natural abundances in a sample of copper. Copper-63 has a natural abundance of 69.17%, while copper-65 has an abundance of 30.83%. Calculating the average atomic mass would involve multiplying the atomic mass of each isotope by its natural abundance, and then summing the results.

How do you calculate the atomic mass of bromine?
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.
How do you use atomic number and average atomic mass to calculate the number of each of the three subatomic particles?
The atomic number is the amount of protons which will equal the amount of electrons. The average atomic mass minus the number of protons will equal the amount of neutrons.
What calculation should be used to calculate the correct average atomic mass of chlorine?
To calculate the average atomic mass of chlorine, you would take the abundance-weighted average of the isotopes of chlorine. This involves multiplying the atomic mass of each isotope by its relative abundance (in decimal form), then summing all the products.
How is the atomic mass of each element on the periodic table calculate?
The atomic mass of an element on the periodic table is calculated by taking the weighted average of the masses of its isotopes, considering the abundance of each isotope in a naturally occurring sample. The atomic mass unit (amu) is used as the unit of measurement for atomic mass.
If the abundance of 85Rb is 72.2 and the abundance of 87Rb is 27.8 what is the average atomic mass of rubidium?
To calculate the average atomic mass of rubidium, you need to take the weighted average of the atomic masses of its isotopes (85Rb and 87Rb) using their respective abundances. Average atomic mass = (85Rb atomic mass * 0.722) + (87Rb atomic mass * 0.278). Using the atomic masses of 85Rb (84.9118 u) and 87Rb (86.9092 u), the average atomic mass of rubidium is approximately 85.47 u.
