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 71, and consists with current knowledge of methyl vinyl ketone, methacrolein, and 2-butenal. The IUPAC name for methyl vinyl ketone is but-3-en-2-one, methacrolein is 2-methylprop-2-enal, and 2-butenal is (2E)-but-2-enal.
