You need more information to answer this, and how you get to the answer will depend on the information available to you.
The balanced equation is 2 Cu(s) + 1/2 O2(g) –> Cu2O(s)
If you have available a table of values of S for different substances, you can calculate Delta S as:
Delta Sreaction = S(Cu2O) – [2S(Cu) + 1/2 S(O2)]
If you have values for Delta G of formation and Delta H of formation of Cu2O, you can use the relationship:
Delta G = Delta H – T Delta S
