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 73.065, and consists with current knowledge of n-butanal, 2-methylpropanal, methyl ethyl ketone, and tetrahydrofuran. The IUPAC name for n-butanal is butanal, 2-methylpropanal is 2-methylpropanal, methyl ethyl ketone is butan-2-one, and tetrahydrofuran is oxolane.
