Aeff=(Zeff)/((Z/A)eff)
Zeff=wi*Zi
wi is weight fraction in ith element in compound. for example water has 0.112 H and 0.888 O.
(Z/A)eff=wi*Zi/Ai
The atomic mass of Mg is 24.3 amu.
It is 20.18
Number of protons plus the number of neutrons (electrons don't matter as they have such a small mass).
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
Cobalt is an atomic mass of 58.93 atomic mass units
The same way you calculate the atomic mass of other elements.
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.
Atomic mass - Atomic number
To calculate the atomic mass of an element, you multiply the mass of each isotope by its relative abundance, then add the results together.
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
The atomic mass of Mg is 24.3 amu.
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
the atomic mass number is the number of protons/electrons in an atom
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.
To calculate the relative atomic mass of an element, you multiply the mass of each isotope of the element by its natural abundance, then add these values together.
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
