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 %
Q:- An impure sample of NaCl, which weighed 0.50 g, gave on treatment with excess of AgNO3 solution, 0.90 g of AgCl as precipitate. Calculate the percentage purity of the sample. Reaction: NaCl + AgNO3 NaNO3 + AgCl. The formula for percentage purity is : (Pure/Total wt.) * 100.
