will learn how to use pycnometer in this assignment. A. Density determination of liquids by pycnometer Density determination by pycnometer is a very precise method. It uses a working liquid with wellknown density, such as water. We will use distilled water, for which temperature dependent values of density ( H2O) are shown in Table 1.
