Calculate the percent composition of each element in a compound.
Percent composition tells you what percentage of a compound’s mass comes from each element.
Percent Composition = (Mass of Element / Total Molar Mass) × 100
This is useful for analyzing chemical formulas, determining empirical formulas, and understanding the makeup of compounds.
Compound: CO₂ Mass of Carbon = 12.01 g/mol Total Molar Mass = 44.01 g/mol Possible Output: Percent Composition of Carbon = 27.29%
