A 53 g sample of impure KClO3 (solubility = 7.1 g per 100 g H2O at 20 degrees C) is contaminated with 13 percent of KCl (solubility = 25.5 g per 100 g of H2O at 20 degrees C).
(a) Calculate the minimum quantity of 20 degrees C water needed to dissolve all the KCl from the sample in grams.
(b) How much KClO3 will be left after this treatment? (Assuming that the solubilities are unaffected by the presence of the other compounds)
