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.

∙ 15y agoBy definition, one mole would be the same as the atomic mass. You take the number of moles and multiply it by the atomic mass. So if you have just 1 mole, the number of grams will be the atomic mass. Magnesium's atomic mass is 24.31 grams.

∙ 9y agoOne mole of magnesium would weight the same as it's molecular weight. One mole of magnesium is about 23 grams.
Wiki User
∙ 13y agoTo find the mass we use the equation m= n x mm. (mass= moles x molar mass). mass = one mole of magnesium x 24.31g/mole. Therefore the mass of one mole of magnesium is 24.31g.

How many grams is 0.348 mol of magnesium?
Molecular mass of magnesium = 24.305 g/mol. 0.478 g/24.305 g/mol = .0197 mols
How many grams of magnesium nitride can be made from 55.3 grams of magnesium if all the magnesium reacts only with nitrogen?
Balanced equation first. 3Mg + N2 -> Mg3N2 55.3 grams Mg (1 mole Mg/24.31 grams)(1 mole Mg3N2/3 mole Mg)(100.95 grams/1 mole Mg3N2) = 76.5 grams Mg3N2 made ===================
What is the number of magnesium atoms that equal a mass of 24.31?
24.31 grams of magnesium is one mole of magnesium, so that is 6.022 X 1023 atoms of magnesium.
What is the mass in grams of 1.501023 atoms Mg?
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
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
There are the same number of atoms in one mole of beryllium as there are in one mole of magnesium :)

How many moles are there in 160g of MgO?
160 grams MgO (1 mole MgO/40.31 grams) = 3.97 mole magnesium oxide =====================
How many grams of sodium contain the same numberof atom as 15grams of magnesium?
Let us find Magnesium atoms first. 15 grams magnesium (1 mole Mg/24.31 grams)(6.022 X 10^23/1 mole Mg) = 3.72 X 10^23 atoms magnesium Now take this an drive to grams sodium 3.72 X 10^23 atoms (1 mole Na/6.022 X 10^23)(22.99 grams/1 mole Na) = 14 grams of sodium ----------------------------
How does the number of atoms in one mole of beryllium compare with the number of atoms in one mole of magnesium?
