So Percent purity is the ratio of the mass of the pure substance to the mass of the impure sample, expressed as a percentage. This is very similar to the percent yield, and to calculate percent purity, we use g pure X 100% g impure Let's try an example. 1.00g Fe ore contains 0.6g Fe metal. What is the percent purity? 0.6/1.0 X 100% = 60 %
