Chemical Formulas

Briefly there are three ways of expressing information about a particular chemical compound: structural formula, molecular formula and empirical formula.

Structural Formula
Structural formula is useful when we need to express information about how atoms are bound to each other.

For example:


Molecular Formula
Molecular Formula is useful when we need to show which and how many atoms a molecule is consisting of.

For example:
H2O

Empirical Formula
Empirical formula gives a simple expression of the ratio of the elements in a compound.

For example:
