Reference
| Temperature (°C) | Density:(g/mL) |
| 18 | 0.9986 |
| 19 | 0.9984 |
| 20 | 0.9982 |
| 21 | 0.9980 |

| 23 | 0.9975 |
| 24 | 0.9973 |
| 25 | 0.9970 |
The relative density was calculated according to the following equation: D4=ps/pw
ps is the density of test item at room temperature
pw is the density of water at 4°C=0.9999
| determinations | weight fatty acids (g) | calculated density (g/cm^3 |
| 1 | 46.2342 | 0.8879 |
| 2 | 46.2255 | 0.8881 |
| Mean | 46.2298 | 0.8880 |
