1. The problem statement, all variables and given/known data

What is the energy (in kJ/mol) of infrared radiation that has a frequency of 1.614 x 107 MHz?

2. Relevant equations

E = nhv

3. The attempt at a solution

3 x 6.63 x 10^-34 (J x s) multiplied by 1.614 x 10^7 (MHz) multiplied by (10^6 Hz/1 MHz) multiplied by (1 kJ/ 1000J) = 3.210246 x 10^-20, which is wrong.

Where is n? You have calculated energy of a single photon.
