Pureza amostra (%)

The sample purity (%) calculator determines the proportion of a pure substance relative to the total mass of a sample. Purity is calculated by dividing the mass of the pure substance by the total sample mass and multiplying by 100. This calculation is vital in chemistry to evaluate the quality of reagents, pharmaceutical products, or materials in laboratories.

To use the calculator, input the mass of the pure substance and the total sample mass. The formula (pure ÷ total) × 100 will be applied automatically. For example, if 85g of pure salt is in 100g of sample, purity is 85%. This helps identify impurities and ensures the effectiveness of industrial processes.

This tool is commonly used in chemical analyses, such as in the pharmaceutical industry to verify the concentration of active ingredients in drugs, or in geology to measure mineral purity. Precautions include ensuring precise mass measurements and noting that impurities can alter results. Avoid use for complex mixtures without separating components.

Calculated purity can influence technical decisions, such as discarding batches below standards or adjusting formulas. In labs, values below 95% might require further purification. Always validate data with complementary analytical methods like chromatography for greater reliability.
