) Calculate the volume (in mL) of nitric acid that you plan to use in Reaction 1 in the procedure. Cu(s) + 4HNO3(aq) -----> Cu(NO3)2 (aq) + 2NO2(g) + 2H2O (l)
2) Calculate the amount of zinc granules (in grams) that must be added in reaction 5 in part 1 of the procedure CuSO4 (aq) + Zn (s) ------> ZnSO4 (aq) + Cu (s)
Additional Information from procedure
1) . Weigh out approximately 0.50 g (starting material) of copper wire or turnings, and record the mass to the nearest 0.01g. Place the copper wire in a 125 mL Erlenmeyer flask. In the bench hood, carefully and slowly add a two-fold excess of concentrated nitric acid (16 M HNO3).
