Empirical Formula of a Compound Experiment 5 Anderson North washbowl Corbin General Chemistry I laboratory Wednesday Night 10/21/09 1) Introduction a) The purpose of this experiment involving semi data-based rules of a compound is to contain the a posteriori jurisprudence of milligram oxide and the share yield in this numerical experiment1. Even though magnesium, an alkaline earth alloy, is the 8th richest metal in the universe and seventh most commons component in the crust of the earth, it is not piece freely in nature4. magnesium, when combined with oxygen at elevated temperatures, ruin into a bright white flame to produce magnesium oxide4. withal referred to as magnesia, magnesium oxide is the second largest compound found in the earths crust. Used in pyrotechnics, flares, and dead bulbs, magnesium oxide is also used in the manufacture of insulating materials, shade metals from their ores, and producing medicines4. Magnesium hydroxi de, formed when water is added to magnesium oxide during heating, is also cognize as the laxative milk of magnesium4. The empirical statute, or simplest formula, is reason development experimental values, while the elements symbols and subscripts recreate the smallest self-colored calculate ratio of atoms in a compound2.

strange molecular formulas, the empirical formula does not imply the read number of atoms in a molecule3. After knocking the empirical formula, the molecular formula can be determined if the hoagie stool of the compound is given3. After calculating the empirical formulas molar mass, molar mass of the compound is divided by th! e empirical formulas molar mass to find the ratio between the two formulas. The subscripts in the empirical formula are multiplied by this ratio and the molecular formula results3. Empirical formulas are calculated using several(prenominal) dissimilar methods. The number one example is calculating empirical formulas from percent compositions using the percents of the different elements.
