The atomic weight of chemical elements is determined by mass spectrometry.
To calculate the mass of an atom, you can add up the masses of its protons, neutrons, and electrons. Protons and neutrons have a mass of about 1 atomic mass unit each, while electrons have a much smaller mass that can usually be ignored. The total mass of an atom is usually given in atomic mass units (amu).
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
Protons and neutrons= mass
To calculate the atomic mass of an element, add up the mass of protons and nuetrons.
To calculate the weight of a mole of an atom in grams (molar mass), you add up the atomic masses of all the atoms in one mole of the substance. This can be found on the periodic table and is usually given in atomic mass units (amu). The molar mass is expressed in grams per mole.
The mass number is the total number of protons and neutrons in an atom's nucleus. To calculate the mass number, simply add the number of protons and neutrons together in the nucleus of an atom.
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
For any given isotope, the sum of the numbers of protons and neutrons in the nucleus is called the mass number. This is because each proton and each neutron weigh one atomic mass unit (amu). By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.

Hey! The excepted banacular is gay. Don't call them atoms that's just mean.
