4. Continuing on with the analysis of the Ni-en complex as found in question #3, 40 mL of dimethylglyoxime, DMG, solution was added to the titrated nickel-en complex solution. The resulting beautiful red complex, Ni(DMG), was collected by filtration and found to weigh 0.232 g. What is the mass (in grams) of Ni in the Ni-en complex analyzed?

Question
4. Continuing on with the analysis of the Ni-en complex as found in question #3, 40 mL of
dimethylglyoxime, DMG, solution was added to the titrated nickel-en complex solution.
The resulting beautiful red complex, Ni(DMG), was collected by filtration and found to
weigh 0.232 g. What is the mass (in grams) of Ni in the Ni-en complex analyzed?
5. Determine the empirical formula of the complex synthesized in questions #3 and #4 above.
6. Assuming 0.900 g of NISO, 6 H,O was used to synthesize the Ni-complex in question 5 and
1.000 g of the Ni-complex formed caleulated the theoretical and percent yield. Refer to the
pre-lab videos for information and examples of these calculations.
