Empirical Formula (Spectrometer Version)

Lab Summary

A major emphasis of laboratory work for a chemist is determining the composition of a compound. There are many tools, such as chromatographic separation and spectroscopy, that aid the chemist in determining chemical composition. By keeping track of mass and breaking a compound into its component pieces, the pieces can be measured and the composition determined.

How do you discover the formula for an unknown substance?

Theory

The student is able to use stoichiometric calculations to analyze the results of a reaction carried out in the laboratory.

Method

The student is able to use data from synthesis or decomposition of a compound to confirm the conservation of matter and the law of definite proportions.
