units of molarity?

The SI unit is mol/m3. However, more commonly the unit mol/L is used. A solution of concentration 1 mol/L is also denoted as "1 molar" (1 M). 1 mol/L = 1 mol/dm3 = 1 mol dm-3 = 1 M = 1000 mol/m3. An SI prefix is often used to denote concentrations. Commonly used units are listed in the table hereafter: Name Abbreviation Concentration Concentration (SI unit) millimolar mM 10-3 mol/dm3 100 mol/m3 micromolar µM 10-6 mol/dm3 10-3 mol/m3 nanomolar nM 10-9 mol/dm3 10-6 mol/m3 picomolar pM 10-12 mol/dm3 10-9 mol/m3 femtomolar fM 10-15 mol/dm3 10-12 mol/m3 attomolar aM 10-18 mol/dm3 10-15 mol/m3 zeptomolar zM 10-21 mol/dm3 10-18 mol/m3 yoctomolar yM[2] 10-24 mol/dm3 (1 particle per 1.6 L) 10-21 mol/m3
