How much energy is contained in 1 mol of each of the following?

X-ray photons with a wavelength of 0.155

How do you do this?

Update:

The first answerer...HUH? i got .1 something for that i don't think thats right.

    Bohr:

    E=N*h*v, E-energy , N- number of photons here, h-Planck constant, v- frequency

    and

    v=c/w v-frequency , w- wavelength, c- speed of light

    therefore:

    E=N*h*c/w

    E=0.155* (6.023*10^23)*(6.6*10^-34)*(2.998*10^8)

    units of the above

    [J]=[mol]*[photons/mol]*[J*s]*[m/s]

    type it into the calculator yourself
