Question

How many moles of CuO can be produced from 0.450 mol of Cu₂O in the following reaction?

2 Cu₂O(s) + O₂(g) → 4 CuO(s)


A) 0.225 mol
B) 0.900 mol
C) 1.80 mol
D) 0.450 mol

Answer 1

0.450 mol

Step-by-step explanation:

To determine the number of moles of CuO produced from 0.450 mol of Cu2O, we can use the stoichiometry of the reaction:

2 Cu2O(s) + O2(g) → 4 CuO(s)

From the balanced equation, we can see that 2 moles of Cu2O react to produce 4 moles of CuO. Therefore, the ratio of moles of Cu2O to moles of CuO is 2:4, or 1:2. So, if we have 0.450 mol of Cu2O, we can calculate the moles of CuO produced by multiplying 0.450 mol by the ratio:

0.450 mol Cu2O × (2 mol CuO / 2 mol Cu2O) = 0.450 mol CuO

Therefore, 0.450 mol of CuO can be produced from 0.450 mol of Cu2O.
