Stoichiometry of Ions
« on: May 19, 2009, 09:11:11 PM »
Hey guys,
I just need a bit of help with this question.

What volume of 0.500 mol/L calcium acetate, Ca(CH3COO)2 (aq), contains 0.300 mol of acetate ions?

I'm not really sure how to start this one out. I wrote out the balanced equation.
Ca(CH3COO2) (aq) -> Ca + 2CH3COO
I know that I have 0.3 mol acetate so 0.15 mol of Ca and Ca(CH3COO2). Not sure what to do next.

One mole of calcium acetate - how many moles of acetate ions?

One litre of 0.5 mole calcium acetate - how many moles of calcium acetate?
