Ni content of the steel can be determined by the precipitation gravimetric analysis. For this purpose, 1.000 g of a steel sample is taken and interacted with the concentrated HCI solution. After neutralizing the resulting mixture in the presence of citrate ions, 1% dimethyl glyoxime (DMG) solution is slowly added to precipitate Ni(II) ions as Ni(DMG)2. What is the percentage of nickel in this steel sample, if 0.2269 g of Ni(DMG), (288.93 g/mol) is obtained?

A 5.70 g iron ore was dissolved in concentrated HCl. After the dissolution, the resulting solution was made basic by adding 6.0 M NaOH slowly until the solution is slightly turbid. Urea was then added and the solution was heated for 3 hours. The precipitate was filtered using an ashless filter paper and ignited to form Fe2O3 (159.69 g/mol). The mass of precipitate is 2.1 g. Find the % Fe3O4 (231.54 g/mol) in the iron ore sample.
