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 ethanolamine, methyl acetate, dimethyl sulfoxide, glycerol, 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 1.0 mL dlo ethanolamine g 0.93 mL methyl acetate dimethyl sulfoxide 1.1 mL glycerol 1.3 mL 0.79 mL acetone Next, the chemist measures the volume of the unknown liquid as 1606. cm° and the mass of the unknown liquid as 1.27 kg Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. |g / mL yes Given the data above, is it possible to identify the liquid? no ethanolamine methyl acetate If it is possible to identify the liquid, do so. dimethyl sulfoxide glycerol acetone

Basic Chemical Calculations (Process and Variables)

A basic chemical calculation involves the application of the law of chemical proportions to various reactions and material and energy balance calculations on various chemical processes. Basic chemical calculation helps students analyze various chemical processes and develop problem-solving skills. The chemical manufacturing processes are divided into unit operations involving physical changes of material and unit processes involving the chemical transformation of materials. For instance, fluid flow, heat transfer, and mass transfer are unit operations, and oxidation, reduction, and pyrolysis are unit processes.
