Question
A chem....rking 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
tetrahydrofuran, chloroform, ethanolamine, diethylamine, and pentane.
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
tetrahydrofuran
-1
0.89 gmL

1.5 g•mL
chloroform
ethanolamine
1.0 g•mL¯
diethylamine
- 1

0.63 g mL
Next, the chemist measures the volume of the unknown liquid as 1062. cm° and the mass of the unknown liquid as 1.08 kg.
Calculate the density of the liquid. Round your
answer to 3 significant digits.
