Question

How many moles of ammonia would be required to react exactly with

0.230 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

The answer would be 0.1533

Answer 2

Answer: 0.1533 moles of NH3

Explanation: The reaction need 2 moles of ammonia and 3 moles of copper oxide to take place. If you have 0.230 moles of copper oxide you need:

0.230/3=0.0767*2=0.1533 moles of NH3
