Fe(s) + Cu^2+(aq)> Fe^2+(aq) +Cu(s)(1)
2Fe(s) + 3Cu^2+(aq)> 2Fe^3+(aq) +3Cu(s) (2)
suppose that you use 1.110 g of Iron in this experiment what is the minimum volume of 1.0M of copper sulfate solution that you should add?
Hint: since you don't know wheteher equation 1 or 2 is the appropriat one you must base your calculations on whichever of tthe equations would require the most copper sulfate for any given quantity of iron?
lol..I tried and subsequently realised I didn't know what I was doing. any help would be appreciated

No. An equation is balanced only if mass is balanced AND charge is balanced. EQuation (2) balances both.
Check the charge changes to verify. 
but she was looking for a numerical answer...are you saying the equation is flawed?
