Asked by Hannah
100 ml of 15 g/L silver nitrate reacts with an unknown concentration solution of copper (ll) chloride. the reaction for me only 2 grams of silver (l) chloride. If 75 mL of the copper (ll) chloride solution was mixed in, what is the initial concentration of the solution?

One of the most poorly worded questions I've seen in some time.
From the description this is a limiting reagent problem in which the CuCl2 is the LR.
2AgNO3 + CuCl2 ==> 2AgCl + Cu(NO3)2
mols AgCl formed = grams/molar mass = ?
mols CuCl2 initially = 1/2 mols AgCl.
(CuCl2) = mols CuCl2/0.175L = ?
