Observed Property: number concentration
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'. This property concerns the isobaric group with atomic mass 69, and consists with current knowledge of furan, isoprene, and cyclopentene. The IUPAC name for furan is furan, isoprene is isoprene, and cyclopentene is cyclopentene.
