The number written in front of a chemical formula is called the coefficient. This represents the number of molecules of the substance in the chemical formula. For example, 8SO3 tells you that there are 8 molecules of SO3 or sulfur trioxide.

∙ 12y agoThe numbers in a chemical formula represent the number of atoms of a particular element. For example water is written as H2O the (2) represents that there are 2 hydrogen atoms and 1 oxygen atom in a water molecule.
Wiki User
∙ 11y agoThe subscripts are the number of atoms of the element, (no subscript means theere is just one).
For example
- H2O- two H ( hydrogen) atoms; one O (oxygen) atom,
- NH3 - one N (nitrogen) atom; three H (hydrogen) atoms
- K2SO4- two K ( potassium) atoms, ; one S(sulfur) atom; four O (oxygen) atoms
