Copper is a product of the reaction that occurs when dry ammonia is passed over a sample of heated copper(II) oxide. The equation for the reaction is given below. 2NH3 + 3CuO --> 3Cu + 3H2O + N2 Calculate the mass of copper produced if 0.12 dm^3 of nitrogen is produced at room temperature and pressure (rtp). (Relative atomic mass of Cu = 64; One mole of gas occupies 24 dm3 at rtp
