The Atomic Mass (also known as atomic weight, though less correctly so) of magnesium represents how many grams are in one mole of magnesium, as is the case with all elements. In short, the atomic mass of magnesium is 24.3050, therefore there are 24.3050 grams of magnesium per mole.
Molecular mass of magnesium = 24.305 g/mol. 0.478 g/24.305 g/mol = .0197 mols
The molar mass of magnesium is 24.31 g/mol and the molar mass of magnesium nitride is 100.93 g/mol. The stoichiometry of the reaction is 3:1 for magnesium to magnesium nitride. Using this information, you can calculate that 55.3 grams of magnesium can produce 151.1 grams of magnesium nitride.
This can be found using one of the most important constants for chemistry: Avogadro's number. According to wikipedia, the standard atomic weight of magnesium is 24.3050 grams per mole. Using Avogadro's number, we know there's 6.0221415 × 1023 atoms per mole, so if you divide the standard atomic weight of magnesium by Avogadro's number, you can get number of grams per atom of magnesium (i.e. the mass of a single magnesium atom in grams). (24.3050 g/mole) / (6.0221415 x 1023 atoms/mole) = 4.03564 g/atom
The molecular mass of magnesium in magnesium chloride is 24.305 grams/mol.
One mole of any element contains Avogadro's number of atoms, which is approximately 6.022 x 10^23 atoms. Beryllium and magnesium are both in Group 2 of the periodic table, so they have the same number of atoms in one mole.
