"The ionization energy of gold is 890.1 kJ/mol. Is light with a wavelength of 225 nm capable of ionizing a gold atom?"

Answer (without detailed steps): λ = 134 nm (Light is

Can someone help me with this question because I don't even know which formula to use for it.

Any help would be greatly appreciated!
Thanks in advance!

How much energy is in a photon of light with wavelength 225nm?

How much energy is required to ionize a single gold atom?
