Atomic Mass of Beryllium
The atomic mass of Beryllium is 9.01 g/mol. The atomic mass of Beryllium is the sum of the masses of all the electrons, protons and the neutrons. Since, there are 4 electrons present in one atom of Beryllium. Therefore, the number of protons are same in number that is 4 to neutralize the -ve charge of electrons. The rest mass addition is due to the presence of neutrons in the atom. The mass of each electron is 9.1x 10-31 Kg. Mass of each proton is 1.67 x 10-27 Kg. The mass of each neutron is 1.67 x 10
-27 Kg.4 x 9.1 x 10-31+ 4 x 1.67 x 10-27 + 4 x 1.67 x 10-27 Kg = 1.33636 x 10-26 Kg = 9.01 g/mol.
The structure and this atomic mass makes the beryllium a useful element for the nuclear processes. The following two reactions shows the nuclear properties of Beryllium:
(1) 94Be + n → 2(42He) + 2nThsi reaction shows the the behaviour of beryllium to release more neutrons in respect to the number of neutrons absorbed by it.
(2) 94Be + 42He → 126C + nBeryllium 7 Atomic Mass
This reaction shows the production of neutrons by hitting of Beryllium nuclei with alpha particles.

In chemistry, the formula weight is a quantity computed by multiplying the atomic weight (in atomic mass units) of each element in a chemical formula by the number of atoms of that element present in the formula, then adding all of these products together.

Finding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula.
Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.
The atomic weights used on this site come from NIST, the National Institute of Standards and Technology. We use the most common isotopes. This is how to calculate molar mass (average molecular weight), which is based on isotropically weighted averages. This is not the same as molecular mass, which is the mass of a single molecule of well-defined isotopes. For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.
If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom (or group of atoms) in the formula by the formula weight and multiplying by 100.
A common request on this site is to convert grams to moles. To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass.
Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance.
