Common units for concentration measurements include mol/L, mmol/L, mg/L, mg/dL, and μg/mL. Others are also used. You need to be able to convert between these measurements readily. (Note that concentrations in mol/L are also called molar, and abbreviated M. A 2.5 mM solution, contains 2.5 mmol/L) Examples:

Consider a 0.300 M solution of NaOH? Calculate the molality of NaOH. (Assume the density of the solution is the same as the density of pure water.) Assume that you have 1 L of solution: Mass of water = mass of solution – mass of NaOH = 1000 g – (0.300 mol)(40 g/mol) = 1000 g – 12 g = 988 g. Molality = 0.300 mol/0.988 kg = 0.304 m
