I want to know the source of this question( The name of the book with the edition) QI/ The calcium in a 200.0-ml. sample of a natural water was determined by precipitating the cation as CaCO. The precipitate was filtered, washed, and ignited in a crucible with an empty mass of 26.6002 g. The mass of the crucible plus CaO (56.077 g/mol) was 26.7134 g. Calculate the concentration of Ca (40,078 g/mol) in water in units of grams per 100 ml of the water. -
