Theoretical yield!!!!!!!! help!?

Question

I have this kind of reaction:

2 Mn + 2 O2 --> 2 MnO2

If Mn is 4 moles and O2 9 moles how much will the theoretical yield be in moles?? I'm not sure if my answer is correct...

A big thank you!!! :)

Answer 1

The ratio between Mn and O2 is 2 : 2 so we will get 4 moles of MnO2 and 5 moles of O2 are in excess

Answer 2
