What is the molarity of a 15%(w/v) solution of nickel (III) ferrocyanide? I can't figure out what nickel(III) ferrocynade is?

Answer 1

ferrocyanide ion is Fe(CN)₆^-4 so Ni₂Fe(CN)₆

Answer 2

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?

Answer 3

No, I'm having trouble figuring the molecular weight of it so I can then figure the molarity.

Answer 4

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