How many moles of ammonia would be required to react exactly with 0.342 moles of copper(II) oxide in the following chemical reaction? 2 NH₃(g) + 3 CuO(s) → 3 Cu(s) + N₂(g) + 3 H₂O(g)

Answer 1

2 NH₃(g) + 3 CuO(s) → 3 Cu(s) + N₂(g) + 3 H₂O(g)

3 mol Cu corresponds to 2 mol NH3(ammonia)

0.342 mol CuO /1 * 2molNH3/3molCuO

0.342(2)/3=0.227mol NH3
