I have like 90% of the Question Done!! Just need help with last step plz :)

The primary wavelength seen by the human eye of most beta fish is 670.0nm. Calculate the energy of 1.50 moles of he photons of this light.

So far, I have E=((6.626x10^-34 J/s)(3x10^8 m/s))/ 670mx10^-9
Which comes out to 2.97x10^-19 J/s (I'm not sure if that's the correct label though)

So what do I do next, how do I use the 1.50 moles of photon?

The Answer according to my teacher is 2.68x10^5 J

Yeah I do, Thanks! I was misplacing the decimal point so I kept getting the wrong answer. Got it now :)
