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, diethylamine, dimethyl sulfoxide, ethanolamine, 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: liquid density -1 0.79 g•mL acetone diethylamine - 1 0.71 g•mL dimethyl sulfoxide -1 1.1 g•mL ethanolamine 1.0 g•mL¯1 glycerol 1.3 g•mL Next, the chemist measures the volume of the unknown liquid as 1530. cm° and the mass of the unknown liquid as 1.08 kg. Calculate the density of the liquid. Round 1- Og. mL your answer to 3 significant digits. Given the data above, is it possible to identify the liquid?

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, diethylamine, dimethyl sulfoxide, ethanolamine, 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:
