摘要
质量浓度、分子浓度、质量摩尔浓度的单位分别为kg/L或kg/m^3、m^(-3)、mol/kg。"浓度"一词作为简称时,只能指物质的量浓度,法定单位为mol/L或mol/m^3。质量分数或体积分数不能简称为"浓度",应用"%"表示。
The unit of mass concentration, molecular concentration and molality is kg/L （or kg/m3）, m-3 and mol/kg, respectively. As an abbreviation, ＂concentration＂ should only refer to amount-of-substance concentration, whose legal unit is mol/L or mol/m3. Mass frac- tion and volume fraction, whose unit is %, can not be referred to as ＂concentration＂ for short.
