8,23.1023 atoms Mg is equivalent to 1,366 moles.
7,00 mg of allicin contain 0,519.10e20 sulfur atoms.
Magnesium nitrate - Mg(NO3)2 - has 9 atoms in the molecule.
From the given elements, Mg has the largest atomic radius, hence the size.
Magnesium chloride (MgCl2) has three elements: magnesium (Mg) and two chlorine (Cl) atoms.

8,23.1023 atoms Mg is equivalent to 1,366 moles.
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.
7,00 mg of allicin contain 0,519.10e20 sulfur atoms.
There are 9 atoms present in one molecule of Mg(NO3)2.
1 gram = 1000 mg
There are two atoms in the formula unit MgO, or magnesium oxide.
Magnesium nitrate - Mg(NO3)2 - has 9 atoms in the molecule.
Magesium phosphide (Mg3P2) has 5 atoms: 3 from Mg and 2 from P.
Mg(C2H3O2)2 or magnesium acetate has one magnesium atom, four carbon atoms, six hydrogen atoms and four oxygen atoms. So a total of 15 atoms per molecule of magnesium acetate.
From the given elements, Mg has the largest atomic radius, hence the size.
