2. A 0.2016 g sample of an unknown Ni(II) salt was put into solution and properly treated to form the solid nickel(II) dimethylglyoxime complex (molar mass=288.917 g mol-¹). When the precipitate was rinsed, dried, and cooled, it was determined to have a mass of 0.1991 g. Calculate the mass of nickel in the precipitate and the percent (by mass) of nickel in the original (unknown) salt sample.
