Units conversion, need help

Reading a scientific study found that:

"were exposed to 10mM"

How much is 10mM?, heard that you must multiply by the molecular weight or something like that...


karma to good answers

depends on what you are researching. MM could be molar mass.
could be milli meters

usually the m is milli. 1x10^-3
.003

Guess its molar, since its a clinical trial.
How to convert to mg?

molar mass has unit of grams/mol

so need to cancel out mol, then you are left with grams. then convert grams to mg(milligrams)
