Molecular Formula. Molecular formula is the formula showing the type of atoms and number of each atom connected in the molecule. Therefore, it gives the correct stoichiometry of each atom. The atoms are depicted by their symbols, which are shown in the periodic table. And the numbers of atoms are written as subscripts.
A formula tells what elements make up a molecule. For example, a molecule of water is made up of two hydrogen atoms and one oxygen atom. The formula for a molecule of water is H2O. Molecules come in different sizes and molecular weights.
