    1. The problem statement, all variables and given/known data
    A carbon-Oxegen double bond in certain organic molecules absorbs radiation that has a frequency of 6.0 x 10^13 s^-1

    A. What is the wavelength of this radiation?
    B. What is the energy of this radiation per photon? per mole of photons?

    2. Relevant equations

    3. The attempt at a solution

    for A I got

    5.0 x 10 ^-6 M

    for B I just don't know how to do it

    I tried using E = hv, and I got 3.9 x 10 ^-20

    Show units in your answers, 3.9x10-20 means nothing.

    M is a molar concentration, I suppose you meant m for meters. If so, you are right in A.
