What is Percent Composition?
Percent composition is the percentage by mass of each element in a compound. It is calculated as: % element = (mass of element in 1 mol / molar mass of compound) × 100%. Percent composition is used to derive the empirical formula of a compound from elemental analysis data. For example, water is approximately 11.19% hydrogen and 88.81% oxygen by mass.
