SInce no one seems inclined to answer your question, I will. However, I
would recommend that you find this type of answer in a textbook as it
should be very easy to find.

a mol is equivalent to 6.02E23 molecules.

therefore a mmol is equivalent to 6.02E20 molecules.
it refers to an absolute number of molecules.

on the other hand, M corresponds to a concentration. That is 6.02E23
molecules per liter. 

therefore a mM concentration is equivalent to 6.02E20 molecules per liter.

hope this helps.
