a. A lab student analyzed a cooled Ni-en complex to determine the ethylenediamine, en, content. A 0.334 g sample of the synthesized Ni-en complex was dissolved in about 50 mL of water and titrated with 0.243 M HCI (aq). Endpoint required 21.01 mL of the HCI (aq). What is the mass (in grams) of en (MW of en = 60.10 g/mole) in the Ni-en complex analyzed? g en + 2 HCI H₂en²+ + 2 CI™ b. Continuing on with the analysis of the Ni-en complex as found in part a, 30 mL of dimethylglyoxime (DMG) solution was added to the 0.334 g of the titrated Ni-en complex solution. The resulting beautiful red complex, Ni(DMG)2 (MW = 288.94 g/mole) was collected by filtration and found to weigh 0.233 g after 20 minutes in the oven.
