How is percentage purity calculated?

• A. Mass of pure substance divided by total mass of sample times 100
• B. Total mass of sample divided by mass of pure substance times 100
• C. Mass of impure substance divided by total mass of sample times 100
• D. Mass of pure element divided by mass of compound times 100

Answer: (A)

Percentage purity is a measure of how much of a sample consists of the desired pure substance as opposed to impurities. To calculate percentage purity, the formula used is the mass of the pure substance divided by the total mass of the sample, then multiplied by 100 to express it as a percentage. This method allows one to quantify the proportion of the sample that is actually the substance of interest, which is crucial in both laboratory and industrial contexts. In this calculation, ensuring that the mass of the pure substance and the total mass of the sample are accurately measured is vital for determining the quality and effectiveness of the sample in various applications. The final result gives a clear indication of how pure the sample is, enabling chemists to assess its suitability for further experiments or processes.
