Raw data of determination:

Weight of pycnometer:

with air: 23.0774 g / 22.5214 g

with deionized water: 47.7484 g /47.4788 g

with solvent: 39.9724 g / 39.6110 g

with sample: 29.6049 g / 28.1191 g

with sample and solvent: 43.3979 g / 42.5516 g

d(4,w) (density of solvent at 20 °C): 0.6835 g/mL

relative density by displacement: 1.4380 / 1.4395 (mean value = 1.439)
