If I put the number and then just \coulomb\per\mole (ex: F=96485.31
\coulomb\per\mole) it would not put the desired space between the
number and the unit. That is why I used the \mathrm. Theoretically,
it would probably be best to use the SIunits \unit command and type
something like \unit{96485.31}{\coulomb\per\mole} but that turns both
the number and the unit into my rm font and everything else around it
is my math font.

I tried putting all those lines (correcting for the last typo) into a
style.sty and opening it after I loaded fontspec.sty in my document
but it didn't change anything. I've attached an exaggerated example
(\setromanfont[scale=1.25]{Palatino}. Look at F. The first time
it's \unit{96485.31}{\coulomb\per\mole}, the second time it's
96485.31 \mathrm{\,\coulomb\per\mole}, and the third time it's
96485.31 \coulomb\per\mole. The last M_Zn is just done straight
65.37 g/mol, which is wrong, but it's there for comparison.
