Review | Constants | Periodic Table
Chemists often use molarity MM, in moles/litermoles/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...
