Find the energy usig plank's constat and wavelenght

What is the energy in joulesnof a mole of protons associated with visible light of wavelenght 486 nm?

Energy = hc/wavelength where h= Planck's constant and c=speed of light. You just need to match units in the equation eg wavelength is in nm and speed of light in m/s
