Table 1: Determining the Density of the Immersion Liquid (IL):
| Mass of Empty Pycnometer (g) | 24.07 | Volume of Pycnometer (ml) | 25.3 |
| Mass water & Pycnometer (g) | 49.34 | Density of Water (g/cm3) (ρW,t) | 0.998 |
| Mass of IL & Pycnometer (g) | 48.44 | Mass IL in Pycnometer (g) (m1) | 24.36 |
| Calculated Density of IL (g/cm3) | 0.963 | Density of IL (kg/m3) | 963 |
Equation 1 (Calculation for the density of water): Mass of water / volume of pycnometer = Density of water .
Equation 2 (Calculation for the density of immersion liquid): ρIL = m1/mW x ρW,t .
Where : m1 is the mass of the immersion liquid, mW is the mass of water, ρW,t is the density of water at temperature t.
Table 2 : Determining the Density of the Sample:
| Run Number | 1 | 2 |
| Mass of Empty Pycnometer (g) | 24.07 | 24.07 |
| Mass of Sample & Pycnometer (g) | 39.83 | 39.51 |
| Mass of Sample added to empty Pycnometer (g) ms | 15.76 | 15.44 |
| Mass of Sample, Pycnometer & immersion liquid | 47.35 | 47.53 |
| Mass of immersion liquid added (g) m2 | 7.52 | 8.02 |
| Calculated Density of Sample (g/cm3) | 0.901 | 0.909 |
| Density of Sample (kg/m3) | 901 | 909 |
Mean Result (kg.m-3): 905.
Equation 3 (Calculation for the density of the sample): ρS,t = ms * ρIL /(m1 – m2) .
Where: ms is the mass, in grams, of the sample; m1 is the mass, in grams, of immersion liquid required to fill the empty pycnometer; m2 is the mass, in grams of immersion liquid added to fill the pycnometer containing the sample; ρIL is the density of the immersion liquid (as determined by equation 2).
Applicant's summary and conclusion
