Mass Spectrometry

This process is an instrumental method in which a sample is changed to fast moving positive ions by electron bombardment. The charged particles vary due to their different mass to charge ratio and are estimated with the help of this difference. It is also called mass spectroscopy.

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 methyl acetate, chloroform, ethanolamine, diethylamine, and tetrahydrofuran. 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 methyl acetate chloroform ethanolamine diethylamine tetrahydrofuran density 0.93 g ml 1.5 g ml 1 -1 1.0 g ml 1 0.71 g ml 0.89 g ml. Next, the chemist measures the volume of the unknown liquid as 1005. cm' and the mass of the unknown liquid as 1.49 kg. Calculate the density of the liquid. Be sure your answer has the correct number of significant digits. Given the data above, is it possible to Identify the liquid?

Dimensional Analysis is a way of doing numerical "book-keeping" when converting quantities or performing calculations. • When converting quantities from one unit to another, conversion factors are used. Solving with Dimensional Analysis and Multiple Units: If I am in Canada where the price of gas is $1.022 USD·L1, how much will it cost me to fill up my gas tank if I travelled 125 km? • Let's also assume that my car gets an average of 30.0 miles/gallon.
