How many moles of CuO can be produced from 0.900 mol of Cu₂O in the following reaction?
2 Cu₂O(s) + O₂(g) → 4 CuO(s)

Question

How many moles of CuO can be produced from 0.900 mol of Cu₂O in the following reaction? 2 Cu₂O(s)+ O₂(g)→ 4 CuO(s) A)0.450 mol B)0.900 mol C)1.80 mol D)3.60 mol

Quizplus · Accepted Answer

From the balanced chemical equation, we can see that 2 moles of Cu₂O produces 4 moles of CuO. Therefore, 1 mole of Cu₂O produces 2 moles of CuO. 0.900 mol of Cu₂O will produce: 0.900 mol Cu₂O x (2 mol CuO / 1 mol Cu₂O) = 1.80 mol CuO. Therefore, the correct answer is C, 1.80 mol.
