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 chemical formula for dichlorodifluoromethane is CCl2F2. It is also called CFC-12 and is a member of the group of halogonated organics known as chlorofluorocarbons (CFCs). The IUPAC name is dichloro(difluoro)methane
