It takes 251 kJ/mol to eject electrons from a certain metalsurface. What is the longest wavelength of light (nm) that can beused to eject electrons from the surface of this metal via thephotoelectric effect?

Anyone can tell me how to solve it step by step so that I willbe able to understand what is going on? :(((

Molybdenum metal must absorb radiation with a minimum frequency of 1.09 × 10¹⁵ s^{- 1} before it can eject an electron from its surface via the photoelectric effect. (a) What is the minimum energy needed to eject an electron? (b) What wavelength of radiation will provide a photon of this energy? (c) If molybdenum is irradiated with light of wavelength of 120 nm, what is the maximum possible kinetic energy of the emitted electrons?
