For the remaining questions, assume that you start with 0.435 g of copper turnings:

Calculate the initial number of moles of Cu.

6.85×10-3 mol Answered

Calculate the minimum volume of 16.0 M HNO3 required to dissolve all of the copper (step 1).

1.71 mL Answered

If, in practice, 5.0 mL of 16.0 M nitric acid were added to effect the dissolution of the copper (step 1), what would be the minimum volume of 4.00 M NaOH required to neutralize the remaining acid and convert all of the Cu2+(aq) to Cu(OH)2(s) (step 2)? Do not know???

Calculate the minimum volume of 1.00 M H2SO4 required to dissolve all of the CuO(s) (step 4). Do not know???

Calculate the minimum mass of zinc required to reduce all of the Cu2+(aq) to Cu(s) (step 5).

(Note that, in practice, a significant excess of zinc is used due to loss of H2(g).) Do not know???
