Water is the most essential compound for living. Life on earth would be difficult without the availability of water. Water is a chemical compound that is made of basic elements of the periodic table.
The elements that constitute water molecules are hydrogen and oxygen. Also, to calculate molecular mass one needs to know the number of atoms present in a molecule.
So, one may wonder how many hydrogen atoms are in a molecule of water?
Let us first know the constituents of the water molecule in brief.
Hydrogen gas is non-toxic and odorless. It is diatomic as there are two atoms of hydrogen combined with a covalent bond. Having molecular formula H2.
It is present on earth in compounds such as hydrocarbons and water.
Oxygen is essential for respiration. It is a colorless and odorless gas. It is present in air and chemical compounds such as water. It is responsible for the combustion process.
How many hydrogen atoms are in a molecule of water?
In a single molecule of water, there are two elements present. The two elements are hydrogen and oxygen atoms. There are in total 3 atoms present in a molecule of water.
The ratio of atoms present is 2:1. Here the two is the number of atoms of hydrogen.
That is there are two hydrogen atoms present and one oxygen atom present in a molecule of water. Hence the molecular formula of water is H2O. The chemical name of water is Oxidane.
The two hydrogen atoms are bonded to one oxygen atom by a covalent bond. The oxygen atom is electronegative and they attract the shared paired of electrons towards itself.
Now that you know how many hydrogen atoms are in a molecule of water, it will be an easier task to do the calculations like the molecular mass of the compound or any other.
