What is the molarity of a 15%(w/v) solution of nickel (III) ferrocyanide? I can't figure out what nickel(III) ferrocynade is?
Answered by DrBob222
ferrocyanide ion is Fe(CN)<sub>6</sub><sup>-4</sup> so Ni<sub>2</sub>Fe(CN)<sub>6</sub>
Answered by DrBob222
That full formula I gave you is for Ni(II), not Ni(III).
But knowing Ni is +3 and ferrocyanide is -4 you can get it, right?
Answered by Beth
No, I'm having trouble figuring the molecular weight of it so I can then figure the molarity.

I have not idea how to work this problem without the grams or the ML of the solution!
