Homework Help: Chemistry

Posted by Kay on Friday, February 17, 2012 at 3:04pm.

To a beaker containing 200 mL of a solution of CuSO4 was added 10.0g of magnesium metal. When the reaction was complete, a mixture of Mg and Cu having a mass of 14.50g remained in the beaker. Calculate the molarity of the original CuSO4 solution.

I understand that I need to get the original number of moles, and to get that, I'm confused. Can I divide the mass of the resultant (14.50g) into 2? But if I do that then reacted line (in a IRF table) doesnt work. Also is the equation CuSO4(aq) + Mg2(s) = Mg2(s) + Cu(s) + SO4(aq)?
