Kinetic energy about a released electron

The work function of an element is the energy required to remove an electron from the surface of the solid. The work function for cadmium is 378.2 kJ/mol (that is, it takes 378.2 kJ of energy to remove 1 mol of electrons from 1 mol of Cd atoms on the surface of a sample of cadmium.) What is the maximum wavelength of light that can remove an electron from an atom in cadmium? (ans in nm.) Answer is 3.163E+02 nm Part 2 of the question is : If solid cadmium is irradiated with 217-nm light, what is the maximum kinetic energy that a released electron can have? (ans in J.) Could you please solve the second part
