    • Calculating percent by mass involves determining the percentage of the mass of a specific element or component within a compound or mixture. To achieve this, you need to know the mass of the element or component and the total mass of the substance. The formula to calculate percent by mass is: (mass of element or component / total mass of substance) x 100.
