Chemists often use molarity m, in moles/liter, to measure the concentration of solutions. molarity is a common unit of concentration because the volume of a liquid is very easy to measure. however, the drawback of using molarity is that volume is a temperature-dependent quantity. as temperature changes, density changes, which affects volume. volume markings for most laboratory glassware are calibrated for room temperature, about 20∘c.
