A 1.000 g sample of nickel ore is dissolved in acid. The nickel(II) ions are precipitated by DMGO (dimethyl glyoxime) solution according to the following equation:Ni2 (aq) 2C4H8N2O2 ? ?i(C8H14ON4O4)2(s) 2H (aq)The precipitate is filtered and washed. Then it is heated gently to dryness. The precipitate weighs 3.601 g. What is the mass percentage of Ni in the ore? Ni(C8H14ON4O4)2 = 288.94 g/mol and C4H8N2O2 = 116 g/mol.Provide work and equations used.
