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
tetrahydrofuran, pentane, carbon tetrachloride, dimethyl sulfoxide, and chloroform.
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
- 3
0.89 g·cm
-3
0.63 g·cm
pentane
-3
1.6 g-cm
carbon tetrachloride
dimethyl sulfoxide
-3
1.1 g'cm
chloroform
1.5 g'cm
Next, the chemist measures the volume of the unknown liquid as 0.893 L and the mass of the unknown liquid as 559. g.
Calculate the density of the liquid. Be sure
your answer has the correct number of
significant digits.
-3
g cm
Given the data above, is it possible to identify
the liquid?
O yes
O no
O tetrahydrofuran
O pentane
O carbon tetrachloride
O dimethyl sulfoxide
O chloroform
If it is possible to identify the liquid, do so.
