How do you find PERCENT purity in calculations

Answer 1

To find the percent purity in a calculation, you need to first determine the actual amount of the pure substance present in a sample and compare it to the total amount of the substance in the sample (which includes impurities).

To calculate the percent purity, you can use the following formula:

Percent Purity = (Actual amount of pure substance / Total amount of substance) x 100

For example, if you have a sample that contains 80 grams of a pure substance and the total amount of substance in the sample is 100 grams, the percent purity would be:

Percent Purity = (80 / 100) x 100 = 80%
