Sorry, osmolality is the term used when measuring osmolarity in body fluids such as blood.

I can’t keep them straight either, I had to do a quick google search to see which was which.

I was expecting an discernible relation to osmosis. Didn’t see that in the definition.

Thanks. I never could keep them straight for any length of time (osmolarity osmolality.) The light goes on for a little while and then goes off.
