student weighs a 1.00-g sample of cadmium chloride and dissolves it in water, then adds aqueous sodium sulfide solution to obtain a precipitate of cadmium sulfide, CdS. The balanced equation for the reaction is CdCl2 (aq) + Na2S(aq) → CdS(s) + 2 NaCl(aq) The student weighs the CdS precipitate and finds that it has an actual mass of 0.775 g. What is the theoretical and percent yield?
