浓度（摩尔）是每升溶液的摩尔数量的度量，通常以每升摩尔（mol/l）测量。
1 mol/L = 100 %mass
1 %mass = 0.01 mol/L
例子:
将15 每升痣转换为质量百分比：
15 mol/L = 1,500 %mass
| 每升痣 | 质量百分比 |
|---|---|
| 0.01 mol/L | 1 %mass |
| 0.1 mol/L | 10 %mass |
| 1 mol/L | 100 %mass |
| 2 mol/L | 200 %mass |
| 3 mol/L | 300 %mass |
| 5 mol/L | 500 %mass |
| 10 mol/L | 1,000 %mass |
| 20 mol/L | 2,000 %mass |
| 30 mol/L | 3,000 %mass |
| 40 mol/L | 4,000 %mass |
| 50 mol/L | 5,000 %mass |
| 60 mol/L | 6,000 %mass |
| 70 mol/L | 7,000 %mass |
| 80 mol/L | 8,000 %mass |
| 90 mol/L | 9,000 %mass |
| 100 mol/L | 10,000 %mass |
| 250 mol/L | 25,000 %mass |
| 500 mol/L | 50,000 %mass |
| 750 mol/L | 75,000 %mass |
| 1000 mol/L | 100,000 %mass |
| 10000 mol/L | 1,000,000 %mass |
| 100000 mol/L | 10,000,000 %mass |
