So sorry thank you for your patients. 10^5 mm

I think I have figured out the total width of the crystal. 10^5 * 11.55nm =

That's what I was thinking.  I wasn't sure if we were precisely interested in finding the molecule's width as well (which I didn't know how to do but had a vague idea of how we might accomplish it).  If this is just for unit conversions though, your answer seems sufficient.  You just need to convert nanometers to millimeters.
