The answer to your question is 39.0392. Try looking this stuff on Google so your don't have to wait for an answer, or you don't get a stupid answer. I once looked up what the mass of an element is and they said "The mass is alot if you got the hand full. On the other hand ..." That and you will get a more detailed answer.
If you were to lazy to read that, the answer is 39.0392.
