A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinet says the cabinet is used to store bottles of carbon tetrachloride, acetone, glycerol, tetrahydrofuran, and ethanolamine,
The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from his collection
of Material Safety Data Sheets (MSDS), the chemist finds the following information:
liquid
density
carbon tetrachloride 1.6g. cm
ole
acetone
0,79 g" C11
glycerol
1.3 g cm
tetrahydrofuran
13
(0,89 g • CHI
ethanolamine
1.0 g. cm
Next, the chemist measures the volume of the unknown liquid as 0.781 L and the mass of the unknown liquid as 617. g.
