Percentage composition= (mass of the element/mass of the molecule)*100
The fraction of the molecule's mass that comes from the element's mass
it tells you how much of the molecule the element is
It tells you how much of a molecule is made up of each element. - APEX
The relative amount of mass an atom contributes to a molecule
^For me :)
Percentage composition tells you the percentage of each element present in a compound or molecule. This allows you to work out the number of atoms of each element present in the molecule.
It tells you what the substance is made of

You can use percent composition to see how much much flour contributes to the mass of an overall cake. You can see how much kool aid powder is in a given amount of kool aid drink, in percentage. Percentage composition can be used for virtually anything that has a mixture of things. So you don't always have to think percentage composition refers to chemical compounds, such as H2O or KMnO4.

A chemical formula tells you the number of each type of atom in the molecule or structure.
A compound formula, or molecular formula, tells you about the chemical composition of the substance in terms of the number of atoms of that element that are present. From there, the empirical formula may also be derived by simplifying the molecular formula, as well as its structural formula.
