This data below applies to question's 24 - 28. A 5.000 g sample of a mixture containing containing Co(NH3)6CI3 was analyzed by "precipitation titration" with silver nitrate solution: Co(NH3)6CI3 (aq) + 3 AgNO3 (aq) –→ Co(NH3)6(NO3)3 (aq) + 3 AgCl (s) A standard solution of AgNO3 was prepared by dissolving 20.00 g of pure AgNO3 in water in a 0.0500 L volumetric flask. The AgNO3 solution was then placed in a buret and used to titrate the sample to the endpoint; the initial buret reading was 0.94 mL and the final reading was 23.14 mL. Using these data, calculate the answers to questions 21 - 25. (You may want to work the answers out on paper before entering them. If you use scientific notation, enter it in "calculator" format, i. e. "1.234e-5")

Based on this question, answer the empty box.
This data below applies to question's 24 28. A 5.000 g sample of a mixture containing containing
Co(NH3)6CI3 was analyzed by "precipitation titration" with silver nitrate solution:
Co(NH3)6CI3 (aq) + 3 AgNO3 (aq)
→ Co(NH3)6(NO3)3 (aq) + 3 AgCl (s)
A standard solution of AgNO3 was prepared by dissolving 20.00 g of pure AgNO3 in water in a 0.0500 L
volumetric flask. The AgNO3 solution was then placed in a buret and used to titrate the sample to the
endpoint; the initial buret reading was 0.94 mL and the final reading was 23.14 mL. Using these data, calculate
the answers to questions 21 - 25. (You may want to work the answers out on paper before entering them. If
you use scientific notation, enter it in "calculator" format, i. e. "1.234e-5")
