A photon of ultraviolet (UV) light possesses enough energy to mutate a strand of human DNA. What is the energy of a single UV photon and 1 mole of UV photons having a wavelength of 32 nm

1 Mol UV Photons = 6.022 x 10^23 UV photons

E of single photon = ? J
E of 1 mole = ? J/mol

I'm still stuck on this and I tried
