If we want to make 5 molecules of water, we need 10 hydrogen atoms and 5 oxygen atoms. The ratio of atoms we will need to make any number of water molecules is the same: 2 hydrogen atoms to 1 oxygen atom.

A single mole of O2 has 6.02 * 10^23 oxygen molecules. Each oxygen has 2 atoms of oxygen. Therefore, 2(6.02 * 10^23) = 1.2 * 10^24.

There are 16 grams of oxygen in 18 grams of water. We can see from the formula for water, H2O, there are twice as many hydrogen atoms (each of atomic mass 1) as oxygen atoms (each of atomic mass 16).

Mass of 1 Mole of Water Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. From the periodic table we see the atomic weight of hydrogen is 1.0079 and the atomic weight of oxygen is 15.9994.

Now by definition, in a mole of stuff there are 6.022×1023 individual items of that stuff. So, in the given quantity of water, there are 6.022×1023⋅mol−1×2.50⋅mol = 15.04×1023 water molecules . How many oxygen atoms in such a quantity; how many hydrogen atoms?

An atom of hydrogen has 1 electron, an atom of oxygen has 8 electrons. Thus, in one molecule of water there are 10 electrons. So, in one mole of water there are 10 moles of electrons.

H2O is a molecule made of H for hydrogen and O for oxygen. There are 12 of these molecules. The smaller number is the number of atoms of the element to the left of it. No number means one atom.

Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water.

1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms.

Each oxygen molecule supplies two oxygen atoms so will always form two water molecules, provided there are two hydrogen molecules (each being a unit of two atoms) to react with it. Thus two molecules of hydrogen and one molecule of oxygen are needed to make two molecules of water.

For example, since one atom of oxygen will combine with two atoms of hydrogen to create one molecule of water (H2O), one mole of oxygen (6.022×1023 of O atoms) will combine with two moles of hydrogen (2 × 6.022×1023 of H atoms) to make one mole of H2O.

The water molecule has a total of 10 protons and 10 electrons (8 from the oxygen atom and 1 from each of the two hydrogen atoms). Since it has the same number of protons and electrons, the water molecule is neutral.

A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.
505236
The second conversion factor reflects the number of atoms contained within each molecule. Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms.

A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms. Sulfuric acid has the chemical formula H2SO4.

If we have 6.02214076×10+23 hydrated copper sulfate molecules and each of these molecules contains exactly nine (9) oxygen atoms, then we expect there to be exactly 9 x 6.02214076×10+23 oxygen atoms in the original sample.

1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms. Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms.
