Acrystallographer measures the horizontal spacing between molecules in a crystal. the spacing is
16.7
nm
. what is the total width of a crystal in millimeters
105
molecules across? write your answer as a decimal.

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.

Yapo 13 fool coming at you for it
