The Percent Purity Calculator is a simple and reliable tool that helps determine the purity of a chemical sample. By comparing the mass of the pure substance to the total mass of the impure sample, this calculator quickly calculates the percent purity to assess the quality of a compound. It is especially useful for chemistry students, laboratory technicians, and researchers who need to evaluate the effectiveness of purification processes or check the concentration of active ingredients. A higher percent purity indicates a cleaner, more refined substance, while a lower value suggests impurities or incomplete purification. Use this easy calculator to improve accuracy in your chemical experiments and analytical work.
