State the crude product is recrystallized

Reference no: EM13188148

A crude product weighing 2.0g contains 0.4g of impurities and is therefore 80% pure. The crude product is recrystallized from 100ml of hot water. Both the desired product and the impurity has a solubility of 0.1g/100ml of cold water. What would be the percent purity after two crystallizations?
