Percent composition is the percent by mass of each element present in a compound

To calculate the percent composition of a component in a compound:

 

1. Find the molar mass of the compound by adding up the masses of each atom in the compound using the periodic table or a molecular mass calculator.

 

2.Calculate the mass due to the component in the compound you are for which you are solving by adding up the mass of these atoms.

 

3.Divide the mass due to the component by the total molar mass of the compound and multiply by 100.

 

Knowing how to find the percent by mass of each element present in a compound will come in handy because you will get to see how much of each ingredient is in a compound or mixture.
