"\"Mole concentration\" means number of moles per unit volume, also called \"molarity\", and is used in the construction \"mole_concentration_of_X_in_Y\", where X is a material constituent of Y. A chemical or biological species denoted by X may be described by a single term such as \"nitrogen\" or a phrase such as \"nox_expressed_as_nitrogen\". \"Nox\" means a combination of two radical species containing nitrogen and oxygen: NO+NO2. The phrase \"expressed_as\" is used in the construction A_expressed_as_B, where B is a chemical constituent of A. It means that the quantity indicated by the standard name is calculated solely with respect to the B contained in A, neglecting all other chemical constituents of A."@en . .
