The Energy of Radiation from a Carbon-Oxygen Double Bond

[I'm]

Homework Statement

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?

Homework Equations

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

Please.

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.
