在GB3102·8-93中,浓度和物质的量浓度是同一个量名称的2种称谓,使用中可以互换,其法定单位为mol/m3或mol/L。这就表明,只有物质的量浓度才可以用浓度替换,其他的量名称都不得称为浓度。然而,在科技书刊中,滥用浓度的现象非常普遍。例如:HCl的浓度为0·5kg/m3;Ca的浓度为0·20;

In GB 3102-8-93, concentration and concentration of substances are two kinds of names of the same quantity, interchangeable in use, the legal unit is mol / m3 or mol / L. This shows that only the concentration of the substance can be used to replace the concentration, the other names are not called the concentration of concentration. However, abuse of concentration is very common in science and technology publications. For example: the concentration of HCl is 0 · 5kg / m3; the concentration of Ca is 0 · 20;
