**Simple energy with photons problem...help!**

## Homework Statement

What is the energy of 1.7 mol of photons that have a wavelength of 0.28 μm?

## Homework Equations

## The Attempt at a Solution

E = HC/W = (6.63e^34)*(3e^8)/0.00000028 = 7.10357e^-21

what do I do with the mol part? I know 1 mol = 6.022e^23 so I tried multiplying it by that but its wrong...do I divide. Or is there something else I have to do?
