N2O is the molecule, so that means within that molecule there is 2 nitrogen atoms and an oxygen atom
The molecular formula for dinitrogen pentoxide is N2O5. This means that each molecule contains 2 nitrogen atoms and 5 oxygen atoms.
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.

hydrogen oxide is water or H2O and has two hydrogens
Five molecules of propane have 40 hydrogen atoms.
dinitrogen pentasulfide N2S5 therefor 5 sulfur atoms
As every nitric oxide molecule has three atoms, this amount of molecules have 3.9 x 1022 atoms.
The chemical formula for nitrous oxide, also known as laughing gas or dinitrogen monoxide, is N2O. That means there are two nitrogen atoms and a single oxygen atom.
A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.

The chemical name dinitrogen tetrafluoride establishes that each molecule contains exactly 2 nitrogen atoms. A mole always contains Avogadro's Number of molecules. Therefore, the required answer is 4.19 X 2 X Avogadro's Number, or 5.05 X 1024 atoms, to the justified number of significant digits.
The molecular formula for dinitrogen pentoxide is N2O5. This means that each molecule contains 2 nitrogen atoms and 5 oxygen atoms.
N2O5 Has a molar mass of 108.01 g/mol 1.73 mol x 108.01 g/mol = 187 grams
This term does not refer to any one compound, because Nitrogen has many oxides: Nitrous Oxide = N2O Nitric Oxide = NO Dinitrogen Trioxide = N2O3 Nitrogen Dioxide = NO2 Dinitrogen Tetroxide = N2O4 Dinitrogen Pentoxide = N2O5 Dinitronitramide(IUPAC name) = N(NO2)3 = N4O6
The name of the compound dinitrogen tetrahydride implies that the formula of the compound is N2H4. Therefore, each molecule contains two nitrogen atoms and four hydrogen atoms.
The chemical formula of aluminium oxide is Al2O3: five atoms.
From the formula, you have 2 atoms of Magnesium combine with one oxygen molecule to form 2 molecules of magnesium oxide. So when 4 magnesium atoms combine with two molecules of oxygen you get 4 magnesium oxide molecules. So from 4 moles of magnesium you get 4 moles of Magnesium oxide.
