# Are empirical and molecular formulas the same?

Jul 24, 2016

In some cases yes, the Empirical Formula and Molecular Formulas can be the same.

#### Explanation:

The Empirical Formula is the lowest whole number ratio of atoms that form the formula of a molecule.

$C {O}_{2}$ $1 : 2$
${H}_{2} O$ $2 : 1$
$C {H}_{4}$ $1 : 4$
${C}_{1} {H}_{2} {O}_{1}$ $1 : 2 : 1$

The Molecular Formula is that actual numbers of atoms that make up the molecule.

$C {O}_{2}$ $1 : 2$
${H}_{2} O$ $2 : 1$
$C 2 {H}_{8}$ $1 : 4$
${C}_{6} {H}_{12} {O}_{6}$ $1 : 2 : 1$
