  skos:note "In chemistry, the name \"amount-of-substance concentration\" is generally abbreviated to the single word \"concentration\", it being assumed that the adjective \"amount-of-substance\" is intended. For this reason, however, the word \"mass\" should never be omitted from the name \"mass concentration\" in <<t9-10>>.\n\nDecided by the 16^th^ CGPM (1979), both \"l\" and \"L\" are allowed for the symbols for the litre.\n"@en ;
