8mmol/mL is equivalent to

8000 mol/mL
8000 mol/L
80 μmol/mL
8mol/L

Just a little stuck so can someone help me figure this out

mmol is milli moles

1000 milli moles in one mole

the mili's can be cancelled out...it's the same as saying

8x10^-3........ mol
-------------------
10^-3.............. L

the 10^-3 can be cancelled


-->8 mol/L
