definition: Number concentration means number of molecule per unit volume, and is used in the construction molecular_concentration_of_X_in_Y, where X is a material constituent of Y. A chemical species denoted by X may be described by a single term such as 'nitrogen' or a phrase such as 'nox_expressed_as_nitrogen'. The chmical formula for dibenz(a,h)anthracene is C22H14. It is a member of the group of polycyclic aromatic hydrocarbons (PAHs). The IUPAC name is naphtho[1,2-b]phenanthrene
