  skos:definition "Mass concentration means mass per unit volume and is used in the construction mass_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 57.033, and consists with current knowledge of acrolein, methylketene. The chemical formula for acrolein is C3H4O, methylketene is C3H4O. The IUPAC name for acrolein is prop-2-enal, methylketene is unknown."@en ;
