How many moles of CuO can be produced from 3.15 mol of Cu2O in the following reaction?

Question

2 Cu2O(s) + O2(g) → 4 CuO(s)

Answer 1

From the balanced reaction, we can see that 2 moles of Cu2O produce 4 moles of CuO.

Therefore, if we have 3.15 mol of Cu2O, we can use the ratio of moles from the reaction:
(4 mol CuO / 2 mol Cu2O) = 2 mol CuO / 1 mol Cu2O

So, 3.15 mol Cu2O * (2 mol CuO / 1 mol Cu2O) = 6.3 mol of CuO

Therefore, 6.3 moles of CuO can be produced from 3.15 moles of Cu2O in this reaction.
