A chemical formula or molecular formula is a way of expressing information about the atoms that constitute a particular chemical compound. The chemical formula identifies each constituent element by its chemical symbol and indicates the number of atoms of each element found in each discrete molecule ...
If there is more than one atom of a type in the molecule, the formula shows it by a small number after the symbol. For example, water isH2O, which means there are 2 atoms of hydrogen and one atom of oxygen in the molecule. Carbon dioxide isCO2, which means there is one atom of c...

The terms true formula and molecular formula are often used interchangeably. The molecular formula for water is written as H2O, where the number two is written as a subscript that represents that a water molecule is composed of two hydrogen atoms, as mentioned earlier in this lesson. Refer to...
Ans: A chemical formula represents a molecule that uses chemical symbols to represent the different types of atoms in the molecule, followed by subscripts to denote the number of each type of atom in the molecule. (When more than one atom of a given type is present, a subscript is used....
(This is somewhat of an academic exercise; the reverse chronology is generally followed in actual practice.) For example, the molecular formula for acetic acid, the component that gives vinegar its sharp taste, is C2H4O2. This formula indicates that a molecule of acetic acid (Figure 6) ...
