11. Dry the precipitate in the oven for about 30 minutes at 120C and determine the mass of the precipitate (subtract the weight of the crucible). Calculations Calculate the mass of nickel (MW 58.7) in 25 mL of a 0.04 M solution of Ammonium nickel(II) sulfate hexahydrate (MW 395.0) Calculate the minimum number of moles of dimethylglyoxime required to fully precipitate the nickel in the solution above Calculate the theoretical weight of the NDMG)2 (MW 288.94) if all the nickel in the 0.04 M solution above was precipitate . Weight of precipitated Ni(dmgH)2 Calculate the molarity of Ni in sample solution
