When Zinc chloride (ZnCl,) reacts with NH, solution, a white crystalline compound Zn(NH,), C, is produced. A student used the procedure in this module to determine the mass percent of NH, in Zn(NH,),CI, The student added 25.00 mL of 0.2500 M HCI solution to an aqueous solution containing 0.3724 g of Zn(NH,),Cl, The excess HCI required 18.80 mL of 0.1000 M NAOH solution for complete titration The student also found that the mass percentage of Zn in the sample is 38.36%. What is the value of n in the empirical formula for Zn(NH,),C
