A note on the door of the cabinet says the cabinet is used to store bottles of methyl acetate, chloroform, ethanolamine, diethylamine, and tetrahydrofuran. 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 methyl acetate chloroform ethanolamine diethylamine tetrahydrofuran density 0.93 g ml 1.5 g ml 1 -1 1.0 g ml 1 0.71 g ml 0.89 g ml. Next, the chemist measures the volume of the unknown liquid as 1005. cm' and the mass of the unknown liquid as 1.49 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? If it is possible to identify the liquid, do so. 0 gml. yes no methyl acetate chloroform ethanolamine…arrow_forwardSays my answer is wrong. Do not give handwriting solution.arrow_forward
