Determine the ionization energy of a hydrogen atom (in kJ/mol) if the electron is in its ground state. (Hints: Use the Rydberg equation, remember E=hc for a single H atom, and R=109678x10–2nm )
I think you meant E = hc/lambda.
Use the Rydberg equation to determine lambda. (lambda = wavelength). Use N1 = 1 and N2 = infinity
E = hc/lambda
That is Joules/atom. Multiply by 6.02 x 10^23 to convert to mols.
