How many moles of CuO would be required to produce 12 mol of copper metal in this reaction? CuO (s) + H2 (g) - - Cu (s) + H2O (g)

12 moles

Explanation:

The equation for the reaction;

CuO (s) + H₂ (g) → Cu (s) + H₂O (g)

We are given;

Moles of copper, Cu is 12 moles

We are required to calculate the number of moles of CuO required;

From the reaction 1 mole of CuO reacts to produce 1 mole of copper Thus, the mole ratio of CuO to Cu is 1 : 1 Moles of CuO = Moles of Cu

Thus, moles of CuO = 12 moles

Therefore; 12 moles of CuO will be required.
