Question

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

Answer 1

0.12 dm^3 x (1 mol/24 dm^3) = ? mols N2
mols Cu = ? mols N2 x (3 mols Cu/1 mol N2) = ?
Then g Cu = mols Cu x atomic mass Cu = ?
