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 dimethyl sulfoxide, ethanolamine, tetrahydrofuran, methyl acetate, and diethylamine. 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 dimethyl sulfoxide 1.1 mL 1.0 mL ethanolamine tetrahydrofuran 0.89 mL methyl acetate 0.93 mL diethylamine 0.71 mL Next, the chemist measures the volume of the unknown liquid as 1655. cm and the mass of the unknown liquid as 1.55 kg. Calculate the density of the liquid. Round 0g / mL your answer to 3 significant digits. O yes Given the data above, is it possible to identify the liquid? O no O dimethyl sulfoxide O ethanolamine O tetrahydrofuran O methyl acetate O diethylamine If it is possible to identify the…
