You need to make a stock solution of a known copper concentration for your experiment. you start by weighing out a piece of pure copper wire which has a mass of 0.211 g. you then add 1.0 ml of 12 m hno3, 3.0 ml of h2o and 2.0 ml of 12 m nh4oh to dissolve the copper metal.
the moles of copper that are in the solution = 0.00332 mols. now i need to find the final molarity of copper in the solution.
