Explanation:
When Zinc chloride (ZnCl2) reacts with NH3 solution a white crystalline compound Zn(NH3)nCI2 is produced. A student used the procedure in this module to determine the mass percent of NH3 in Zn(NH3)nCl2) The student added 25.00 ml of 0.2500 M HCl soution to an aqueous solution containing 0.3724 g of Zn(NH3)nCl2. The excess HCl 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 38.38%. What is the value of n in the empirical formula for Zn(NH3)nCl2
