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 |
