How do you find the percent composition?
Percent Composition
- Find the molar mass of all the elements in the compound in grams per mole.
- Find the molecular mass of the entire compound.
- Divide the component’s molar mass by the entire molecular mass.
- You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.
