∙ 13y ago
The 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.
What information about an element's isotopes is needed to calculate that element's average atomic mass?

How do you calculate atomic mass unit of gold?
The atomic mass unit (amu) is a unit of mass used to express the average mass of an atom or molecule. To calculate the atomic mass unit of gold (Au), you would look at the atomic mass of gold on the periodic table, which is approximately 197 amu.
What is needed to find the average atomic mass of the element?
To find the average atomic mass of an element, you need to know the isotopic masses of each of its isotopes and their relative abundances. Multiply the isotopic mass of each isotope by its relative abundance, then sum these values to calculate the average atomic mass.
What is the average atomic mass of an element with two isotopes of 220 and 250?
To calculate the median atomic weight, the relative abundance of each isotope could be calculated or given.
Chlorine has 2 isotopes and These have atomic masses 34.9689 amu and 36.9659 amu respectively Their ratio in nature is 75.77 percent and 24.23 percent respectively Calculate the average atomic ma?
To calculate the average atomic mass of chlorine, you can use the formula: (mass of isotope 1 * abundance of isotope 1) + (mass of isotope 2 * abundance of isotope 2). Using the given values, the average atomic mass of chlorine would be: (34.9689 amu * 0.7577) + (36.9659 amu * 0.2423) = 35.453 amu.
How do you calculate the atomic mass of thalium?
