A note on the door of the cabinet says the cabinet is used to store bottles of pentane, dimethyl sulfoxide, acetone, methyl acetate, and chloroform. 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 0.63 mL pentane db dimethyl sulfoxide 1.1 0.79 acetone 0.93 mL methyl acetate 1.5 chloroform 3 Next, the chemist measures the volume of the unknown liquid as 1797.…
