The atomic mass of Mg is 24.3 amu.
The average atomic mass of an element is the average of the atomic masses of its isotopes (that is a weighted average). You have to take into account the abundance of each isotope when they do your averaging.
What is weighted average atomic number
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.
Scandium is a meta element. Atomic mass of it is 45. Atomic number of it is 21.
That is the average atomic mass for Mg.
Add the atomic masses of each element present. It would be atomic mass of Mg + 2x atomic mass of oxygen + 2x atomic mass of hydrogen.
The atomic mass of Mg is 24.3 amu.
Mg: 24.305 K: 39.0983
Atomic mass is the number of protons and neutrons in an atom.
No, the atomic mass is the average mass of the atom and the atomic diameter is the average diameter of the atom
Magnesium is a meta element. Atomic mass of it is 24.
the Atomic Mass
The Atomic Mass of Mg is 24. The atomic mass of fluorine is 19. Therefore the relative mass of the substance is 62.
The average atomic mass of Lithium (Li) is 6.941.
The average atomic mass of nitrogenis 14.0067.
"Atomic Mass" is not an average, it is tje total mass of all the electrons, protons and neutrons in an atom of an element. AVERAGE Atomic Mass is the AVERAGE of the Atomic Masses of all of the Isotopes of an element according to their natural proportions.
