Per Cent concentration drug calculations

I freaking tried to contact the Tennessee Board of Nursing. Those lame-os are closed for the holiday...

Yeah, I saw your post on FB. They close for all sorts of weird pseudo-holidays

Stolen from Wikipedia's article on saline.




If you post below applies to medications saline would have 9 moles per liter, which it doesn't.

For some dad gum reason I had 1 mole = 1 gram stuck in my head. This would only apply to hydrogen which is about 1 gram per mole. Now after looking at a periodic table I see how far off base I was as each element has a different mass per mole. Saline for example; Sodium Na = 22.98g/mol and
Chloride Cl = 35.4g/mol so NaCl molar weight is ~58g/mol as you pointed out.
Don't I feel silly. Embarrassing part is that I was so certain. Geez:blush:
