When 80.4 moles of calcium acetate are
dissolved in enough water to make 222.2
milliliters of solution, what is the molarity of acetate ions?
Answer in units of M
I already tried moles/liter and it was wrong
Sarah, Nick, Joe -- you must be having an identity crisis.
Please use only one name for your posts.
I expect you calculated M Ca(Ac)2. Take your answer for mols Ca(Ac)2 and multiply by 2 to find mols Ac^-.
(80.4/0.2222)*2 = ? and watch the number of significant figures.
