The mole is the quantitative basis for comparing
substances.
Elements chemically combine in set ratios.
Percent composition of a compound is also based on
the substance’s mole-to-mole ratio.
The valence shell electrons predict a substance’s
chemical properties.
Elements chemically combine in ratios that yield a
total charge of zero.
Safety considerations are critical to a student’s
understanding of science.
Errors in measurement have a major effect on the
validity and accuracy of scientific investigations.

Empirical Formula Laboratory
Magnesium Oxide lab
Experimentally determine the empirical formula of magnesium
oxide by heating magnesium ribbon in a crucible.
1. Using the mass of the magnesium oxide formed and the amount of
original magnesium ribbon, calculate the empirical formula for
magnesium oxide.
2. Repeat procedure.
3. Obtain data from two other lab groups and perform statistical
analysis to calculate the percent composition and empirical formula
of magnesium oxide.
4. Write the lab report to include an overview of the mole theory, a
discussion of the procedure, the type of reaction that occurred,
important observations and conclusions, complete calculations
(dimensional analysis, significant figures, etc.), and formula names
and formulas in the analysis of the experiment. Be sure to relate
results and observations to an explanation of how an atom’s
electron configuration affects its ratio to another element when they
chemically combine.
