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.
Since dinitrogen pentoxide has the chemical formula N2O5, it contains two nitrogen atoms. Therefore, for every molecule of N2O5, there are two molecules of N2O. In 2.88 moles of N2O5, there would be 2.88 x 2 = 5.76 moles of N2O. Finally, since 1 mole of N2O contains 2 molecules of N2, there would be 5.76 x 2 = 11.52 moles of N2 molecules.
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.

K2O: 3 atoms in the molecule K2O2: 4 atoms in the molecule KO2: 3 atoms in the molecule
dinitrogen pentasulfide N2S5 therefor 5 sulfur atoms
There are two atoms of nitrogen in each molecule of dinitrogen tetroxide.
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.
The molecular formula for dinitrogen pentoxide is N2O5. This means that each molecule contains 2 nitrogen atoms and 5 oxygen atoms.
If 8 atoms of iron react with 6 molecules of oxygen, they will form 4 units of iron oxide (Fe2O3) because each molecule of iron oxide contains 2 atoms of iron and 3 atoms of oxygen.
One molecule of iron oxide (Fe2O3) contains two iron atoms per molecule. So, for every molecule of iron oxide, there are two iron atoms, which means one iron oxide molecule contains two iron atoms.
Since dinitrogen pentoxide has the chemical formula N2O5, it contains two nitrogen atoms. Therefore, for every molecule of N2O5, there are two molecules of N2O. In 2.88 moles of N2O5, there would be 2.88 x 2 = 5.76 moles of N2O. Finally, since 1 mole of N2O contains 2 molecules of N2, there would be 5.76 x 2 = 11.52 moles of N2 molecules.
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.
If you're referring to N2O, it's nitrous oxide. It's also known as "laughing gas," and is administered at many dentist offices (and other surgical locations). There are dangers involved with this gas, so you shouldn't use it without a medical professional present.
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.
N2O5 Has a molar mass of 108.01 g/mol 1.73 mol x 108.01 g/mol = 187 grams
The chemical formula of aluminium oxide is Al2O3: five atoms.
