    The density of room temperature ionic liquids (RTILs) at ambient pressure but over a temperature range can be estimated sufficiently accurately from the ionic volumes of the constituent ions with just two universal parameters. The ionic volumes of inorganic ions are well established, and those of alkyl-substituted imidazolium, pyridinium, pyrrolidinium, quaternary ammonium and phosphonium cations and sulfate anions are linear with the number of carbon atoms in the chains. The molar volumes of liquid RTILs are larger than Avogadro's number times the sum of the ionic volumes of cations and anions because of the expansion of the crystalline solids on melting and the creation of ion-sized cavities.
