Question
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 pentane, chloroform, ethanolamine, diethylamine, and acetone.
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
