I solved it. I had to convert before doing the E-photon and E-released.

Okay... so what am I missing? Avagadro's number maybe?

An X-ray photon of wavelength 0.940 nm strikes a surface. The emitted electron has a kinetic energy of 947 eV. What is the binding energy of the electron in kJ/mol? What I did: (947 eV)(1.602E-19 J)/1 eV = 1.52E-16 J(6.626E-34 J.s)(3.0E8 m/s)/.940 nm (10^-9m/1 nm) = 2.11E-16 J 2.11E-16 J -...
