Question

O MATTER Calculating mass density A chemist working as a safety inspector finds an unmarked bottle in a lab cabinet. A note on the door of the cabinlet says the cabinet is used to store bottles of glycerol, chloroform, acetone, ethanolamine, 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: density glycerol 138-cm hloroform15 8 Cm acetone 0.79 gm ethanolamine 1.0 gcm pentane 0.63m liquid -3 -3 Next, the chemist measures the volume of the unknown liquid as 0.618 L and the mass of the unknown tiquid as 629. Calculate the density of the liquid. Round your answer to 3 significant digit Given the data above, is it possible to identify y the iquid? O no chiarolrm it it is possible to identily the iquid, do sotne ethandl pentane
