Mg(oh)2 contains of Mg,O and h atoms. There are 3 atoms in 1 Mg(OH)2. So there are 12 atoms in 4Mg(OH)2.
2 Magnesium OR Iron atoms to 1 Silicon, 4 Oxygen atoms. A formula of (Mg, Fe)2 Si O4
O2 has 2 atoms of oxygen.
4 hydrogen atoms 4 nitrogen atoms 12 oxygen atoms
2x2= 4 hydrogen atoms (2x1= 2 oxygen atoms).
Fe3O4 has a total of 7 atoms, with 3 iron atoms (Fe) and 4 oxygen atoms (O).
In 4 moles of magnesium hydroxide, Mg(OH)₂, there are a total of 20 atoms. Each formula unit of Mg(OH)₂ contains 1 magnesium atom, 2 oxygen atoms, and 2 hydrogen atoms, totaling 5 atoms per unit. Therefore, for 4 moles, you calculate 4 moles × 5 atoms/mole = 20 atoms.

There are a total of 6 atoms in 2Mg(NO3)2. This includes 2 magnesium (Mg) atoms, 4 nitrogen (N) atoms, and 12 oxygen (O) atoms.
There are six atoms (or technically, ions) in magnesium sulphate: one Mg ion, one sulphur and 4 oxygen ions.
4 mg = 4,000 mcg
In the compound Mg3(PO4)2, there are 3 magnesium (Mg) atoms, 2 phosphorus (P) atoms, and 8 oxygen (O) atoms (since each phosphate group, PO4, contains 4 oxygen atoms and there are 2 phosphate groups). To find the total number of atoms, you add these together: 3 (Mg) + 2 (P) + 8 (O) = 13 atoms in total.
4 ounces = 113,398.093 milligrams.
To find out how many 0.5 Mg (megagrams) are in 2 Mg, you divide 2 Mg by 0.5 Mg. This calculation gives you 2 Mg ÷ 0.5 Mg = 4. Therefore, there are 4 units of 0.5 Mg in 2 Mg.
40 mg
4000 mcg (micrograms) equals 4 mg (milligrams)
0.4 mg = 0.0061729 grains.
Well, there are 1000 mg in 1 gm...
