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, diethylamine, carbon tetrachloride, acetone, and glycerol. 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 ethanolamine 1.0 mL diethylamine 0.71 mL g 1.6 mL carbon tetrachloride 0.79 mL acetone g 1.3 mL glycerol Next, the chemist measures the volume of the unknown liquid as 1378. cm2 and the mass of the unknown liquid as 1.40 kg. Calculate the density of the liquid. Round X10 g/mL your answer to 3 significant digits. ? X yes Given the data above, is it possible to identify the liquid? no

Calculate mass density with conversions (I attached picture) 

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, diethylamine, carbon tetrachloride, acetone, and glycerol.
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:
