Calculate the amount of Ni2+ ions in given solution where
Mass of empty sintered glass crucible = 15.6379 g
Mass of empty sintered glass crucible + Ni-DMG after first heating = 15.6528 g Mass of crucible after second heating = 15.6520 g
Mass of crucible after third heating = 15.6520 g
Mass of sintered glass crucible = a g.
Mass of sintered glass crucible + nickel complex = b g.
Mass of dimethyl glyoxime nickel complex = (b-a) g.
288.69 of nickel complex contain 58.69 g of nickel.
Mass of nickel in (b-a) g of complex .
Therefore, Mass of nickel in the whole of the given solution .
