When zinc chloride (ZnCl2) reacts with NH3 solution, a white crystalline compound, Zn(NH3),CI2, is produced. A student used the procedure in this module to determine the mass percent of NH3 in Zn(NH3),,CI2. The student added 25.00 mL of 0.2500M HCl solution to an aqueous solution containing 0.3724 g of Zn(NH3),C12. The excess HCl required 18.80 mL of 0.1000M NaOH solution for complete titration. The student also found that the mass percentage of Zn in the sample is 38.36%. What is n in the empirical formula for Zn(NH3),C12?

3. A student followed the procedure of this experiment to determine the percent NaOCl in a commercial bleaching solution that was found in the basement of an abandoned house. The student diluted 50.00 mL of the commercial bleaching solution to 250 mL in a volumetric flask, and titrated a 20-mL aliquot of the diluted bleaching solution. The titration required 35.46 mL of 0.1052M Na,5203 solution. A faded price label on the gallon bottle read S0.79. The density of the bleaching solution was 1.10 g mL-? h. Calculate the mass of one gallon of the commercial bleaching solution. i. Calculate the cost of 100 g of the commercial bleaching solution. j. Determine the cost of the amount of commercial bleaching solution required to supply 100 g of NaOCl.
