Question
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 acetone, methyl acetate, carbon tetrachloride, chloroform, and dimethyl sulfoxide.
The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First, from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information:
Transcribed Image Text: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 acetone, methyl acetate, carbon tetrachloride, chloroform, and dimethyl sulfoxide.
The chemist plans to try to identify the unknown liquid by measuring the density and comparing to known densities. First,
from her collection of Material Safety Data Sheets (MSDS), the chemist finds the following information:

Next, the chemist measures the volume of the unknown liquid as 0.790 L and the mass of the unknown liquid as 738. g.
Calculate the density of the liquid. Be sure
your answer has the correct number of
significant digits.
IIg / cm
Given the data above, is it possible to identify
the liquid?
yes
no
acetone
methyl acetate
If it is possible to identify the liquid, do so.
carbon tetrachloride
chloroform
dimethyl sulfoxide
