### on the outside and weighed again (B). I I The density ofi the liquid test substance was catculated from the difference in weight between I

the full (C) and empty pycnometer (mean A) and its known votume {mean % This procedure was repeated until reproducible results (deviation in the density s 0.01 g/cm ) were obtained. ~ • •
