Percent Composition - The percent composition of a component in a compound is the percent of the total mass of the compound that is due to that component.
THE PERCENTAGE BY MASS OF AN ELEMENT IN A COMPOUND IS ALWAYS THE SAME.
- to find the percentage by mass, determine the mass of each element present in one mole.
The percent composition (percentage composition) of a compound is a relative measure of the mass of each different element present in the 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.
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.
