    The blue color of the sky is due to the scattering of sunlight by the molecules in the air. The blue light has a frequency of about 7.5 x 10^14 Hz.
    A. Calculate the wavelength, in nm, associated wth this radiation.

    I believe the correct formula for this part is speed of light (299,792,458 m/s x 7.5 10^14 Hz).

    B. Calculate the energy, in joules, of a single photon associated with this frequency.

    I do not understand how to set this portion of the problem up.

    C. Calculate the energy, in KJ, of 1 mole of these photons.

    Unable to do because I do not understand how to do part B.
