When zinc chloride (ZnCl2) reacts with NH3 solution, a white crystalline compound Zn(NH3)12Cl2 is produced. A student used the same procedure as the one you used to analyze Ni(NH3)12Cl2 to determine the mass percent of NH3 in Zn(NH3)12Cl2. The student added 25.00 ml of 0.2500 M HCI solution to an aqueous solution containing 0.3146 g of Zn(NH3)12Cl2. The excess HCI required 25.60 ml of 0.1000 M NaOH solution for complete titration. Calculate the mass percent of NH3 in Zn(NH3)12Cl2 based on the student's data.
