In the realm of chemistry, mass percentages are used to denote the concentration of a particular element within a mixture or compound. This is calculated by taking the mass of the element, dividing it by the overall mass of the mixture and subsequently multiplying by 100%. This vital concept aids in comprehending the concentration of a solution and stoichiometry.
