12.) A 2.00g sample of limestone was dissolved in hydrochloric acid and all the calcium present in the sample was converted to Ca²+o): Excess ammonium oxalate solution, (NH,),C¸Ɔ(ag), was added to the solution to precipitate th e calcium ions as calcium oxalate, CaC,0(s). The precipitate was filtered, dried and weighed to a constant mass of 2.43g. Determine the percentage by mass of calcium in the limestone sample.
