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 chloroform, diethylamine, ethanolamine, acetone, and pentane. 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 chloroform diethylamine 0.71 1.58 mL ethanolamine 1.0 acetone pentane 0.79 0.63 mL g mL g mL mL Next, the chemist measures the volume of the unknown liquid as 1362. cm³ and the mass of the unknown liquid as 2.02 kg. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Given the data above, is it possible to identify the liquid? g/mL yes no X
