The Mg in 400ml sample of a natural water was determined by precipitating the cation as MgC204. The precipitate was filtered, washed an ignited in a crucible with empty mass of 25.4002 g. The mass of the crucible plus MgO ( 40.304 g/mol) was25.5134g.Calculate the concentration od Mg (24.305 g/mol) in water in units of grams per 100ml of water.
