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 %
What is melting point? Why can it be used as an index of purity? Melting point is one way of determining whether a substance is pure or not (Bodner Research Web, 2016). In determining the melting point, the range of temperature is the basis. This means the temperature at which the compound changes its state from solid to liquid.
