Abstract
The mass measurement of the water content of a pycnometer is done in the same way as a mass measurement of a solid artefact. There are many types of pycnometers, among them there are the Gay-Lussac types, and within the latter there are those with an anti-evaporation cap and those without. Pycnometers without a cap let the water evaporate during the measurement process. Yet it is possible to measure the mass of the full pycnometer by extrapolating backward in time from the weighing measurements taken over a period of time. The analysis of the process is presented here as well as the advantages of using this method over the usual one of a single quick weighing of the artefact.
