Simple calculation -- am I dain bread?

[fbrdphreak]

I'm calculating the energy of a photon and found the equation on a website:
http://www.science.uwaterloo.ca/~cchieh/cact/c120/emwave.html

Here's the sample they give:

(6.626e-34 * 3e8) / (550e-9) = 2.18e8

When I plug it into my TI-89, I get 361.418e-21

I don't think any settings are wrong in my calc, wtf?

Your answer is right. There's no way the energy of a single photon is ~10^8 Joules. The answer they give is per mole of photons.
