Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.

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 glycerol, carbon tetrachloride, pentane, tetrahydrofuran, and acetone. 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 glycerol -3 1.3 g-cm - 3 1.6 g cm carbon tetrachloride -3 0.63 g·cm pentane tetrahydrofuran -3 0.89 g·cm -3 0.79 g·cm acetone Next, the chemist measures the volume of the unknown liquid as 0.786 L and the mass of the unknown liquid as 991. g. Calculate the density of the liquid. Round your g. cm answer to 3 significant digits. yes Given the data above, is it possible to identify the liquid? no glycerol carbon tetrachloride pentane If it is possible to identify the liquid, do so. tetrahydrofuran acetone
