A standard solution of FeCl3 was prepared and its molar concentration was determined to be 2.000 M. This solution was labeled as solution A. Then a 10.00-mL aliquot of solution A was added to a 50.00-mL solution of CoCl2 of unknown molarity. This solution was labeled as solution B. Finally, 25.00 mL of solution B was transferred to a 500.00-mL volumetric flask and distilled water was added to the calibration mark. This solution was labeled as solution C. If the concentration of the chloride ions in solution C was found to be 0.08335 M, calculate the molarity of the CoCl2 solution.

I need answer for question 2
Transcribed Image Text:A standard solution of FeCl3 was prepared and its molar concentration
was determined to be 2.000 M. This solution was labeled as solution A.
Then a 10.00-mL aliquot of solution A was added to a 50.00-mL solution
of CoCl2 of unknown molarity. This solution was labeled as solution B.
Finally, 25.00 mL of solution B was transferred to a 500.00-mL volumetric
flask and distilled water was added to the calibration mark. This solution
was labeled as solution C.
If the concentration of the chloride ions in solution C was found to be
0.08335 M, calculate the molarity of the CoCl2 solution.
