the Atomic Mass number is the number of protons/electrons in an atom
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 of Mg is 24.3 amu.
the Atomic Mass number is the number of protons/electrons in an atom
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.
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
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.
The atomic mass of a substance is the mass of one mole of that substance. To calculate the atomic mass of 25 mg of a specific element, you would first need to determine the molar mass of that element. You can then use the molar mass to convert the mass of the sample (25 mg) to the number of moles, and then calculate the atomic mass of that amount.
