Chemists often use molarity M, in moles/liter, tomeasure the concentration of solutions. Molarity is a common unitof concentration because the volume of a liquid is very easy tomeasure. However, the drawback of using molarity is that volume isa temperature-dependent quantity. As temperature changes, densitychanges, which affects volume. Volume markings for most laboratoryglassware are calibrated for room temperature, about 20?C.
Fortunately, there are several other ways of expressingconcentration that do not involve volume and are thereforetemperature independent.
