A [['''chemical compound]] ''' is any substance that consists of two or more [[chemical element]]s always associated with one another in the same proportion, and that has certain properties deriving from that association that define and distinguish it from other substances.<ref>Wile, Dr. Jay L. ''Exploring Creation With Chemistry''. Apologia Educational Ministries, Inc. 1998</ref>
A compound is one example of a [[pure substance]]. (The other is a [[chemical element]].)
In general, polar solutes dissolve in polar solvents, and nonpolar solutes dissolve in nonpolar solvents. Ionic compounds (see above) typically dissolve only in polar solvents.
Molecular compounds are also either ''organic'' or ''inorganic''. [[Organic compound]]s contain carbon; inorganic compounds do not. Polyatomic ions may also be organic or inorganic -- though inorganic—though an organic polyatomic ion is usually a dissociated weak organic acid of the form R-COOH, where R is the rest, or ''residue'', of the molecule.

====Molar mass====
The ''Molar mass is the quotient of the mass ''m'' and the feel quanty ''n''. Molarity is defined as mass of the substance of interest (the "solute") per unit volume of the "solvent" (whatever the substance is being measured with respect to) at an arbitrary a given temperature, and is therefore subjective; whereas molality . ''Molality'' is defined as mass of solute per unit massof the solvent, and is thus wholly objectivenot affected by density changes. [[User:ThatSunsHot|ThatSunsHot]] 19:36, 18 November 2014 (EST)
