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 ethanolamine, pentane, chloroform, acetone, and glycerol. 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 1049. cm and the mass of the unknown liquid as 1.07 kg.

Next, the chemist measures the volume of the unknown liquid as 1049. cm and the mass of the unknown liquid as 1.07 kg.

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
ethanolamine, pentane, chloroform, acetone, and glycerol.
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

Next, the chemist measures the volume of the unknown liquid as 1049. cm and the mass of the unknown liquid as 1.07 kg.
Calculate the density of the liquid. Round
your answer to 3 significant digits.
Given the data above, is it possible to
identify the liquid?
If it is possible to identify the liquid, do so.
