  1. 6.00 mol of copper, Cu, are mixed with 12.00 mol of dilute nitric acid, HNO₃ (aq). The equation for the reaction that occurs is shown below.

3Cu(s) + 8HNO₃(aq) → 3Cu(NO₃)₂(aq) + 2NO(g) + 4H₂O(l)

What is the amount, in mol, of nitrogen(II) oxide, NO, produced assuming that the reaction goes to completion?
