0.1mg/ml=?PPM

0.1mg/ml=?PPM 1mg/ml是1000ppm还是100ppm?急, 1ppm=2.144mg/m3 =0.1mg/m3 g/100ml 与ppm的换算1g/100ml=10000ppm?那么1ppm=1mg/l? ppm换算mg m3,37000ppm= mg/m3 PB标准溶液C=1MG/ML怎样稀释成含PB0.2PPM溶液 ppm=mg/kg 问 10ppm=10mg/mg吗? 1ppm=1mg/kg=1mg/L 哪么1ppm=多少ug/g=多少ug/mL 50μg/ml 磷标准溶液=（ ）ppm磷标准溶液?μg/ml、mg/L、ppm这3个单位是相等的吗? 0.1mg/m3=多少mg/ml 1ppm=0.1mg/100g吗 500g/ml=?ppm 28ppm的Cl-相当于多少mg/ml? 化学代号Mg/kg=ppm是什么意思 20ppm=?mg/L如题 ppm、ppb、pptppm=mg/kg,ppb=ng/g,ppt=?ug/ml又是什么的单位?大家能不能告诉我一个系统的单位换算?例如：ppm=mg/kg=ug/l=.=... 0.0001g/ml=多少ppm
