Table 2 Measurement and calculation of the density liquids with pycnometer. Weighing. Result m0. (g) m2 = m0 + mH2O. (g). mH2O. (g) m3. (solution 1). (g). mL. |
Therefore, according to equation [1], the density of an object depends on its temperature, with higher temperature resulting in lower density. The density of a ... |
Videolar In this case the following three weighings are made: 1. m1* mass of the pycnometer filled with distilled water 2. m3* mass of the pycnometer filled with air 3. ... |
Density is merely calculated as the ratio of mass to volume; mass being invariably measured on a discrete device, usually by weighing. |
When the mass of the sample is known before the measurement, the density can be calculated simultaneously. A simplified diagram of a gas pycnometry setup. |
Essentially, glass pycnometers measure the unknown mass of a liquid – this mass is then divided by the known volume of the pycnometer to determine the density ... |
8) Measure the weight of pycnometer filled with your substance at the analytical balance 9) Use the equation (density) = (mass) / (volume) to determine density ... |
