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–1 )
_____ kJ/mol
Thanks :)

DrBob222,
1/wavelength = R(1/n1^2  1/n2^2)
n1 = 1
n2 = infinity which makes 1/n2^2 = 0 so you have
1/wavelength = R(1)
Calculate wavelength.
Then E = hc/wavelength.
Solve for E in J. That will be for 1 atom. Multiply by 6.022E23 to convert to J/mol and convert that to kJ/mol.
