1. The problem statement, all variables and given/known data Calculate the mass corresponding to the binding energy of an H atom. What fraction of the mass of the atom is this? 2. Relevant equations BE=(mp+me-mH)c2 3. The attempt at a solution I couldnt figure this one out, so I searched for the answer online, and it's supposed to be 13.6 eV, but no matter what I do, none of my answers come even close to that.
