Jake Smith CHE LAB 111-009 Karimi Fariba Kacey Rocazella October 4, 2011 Empirical Formula Experiment Finding the Empirical Formula of Copper Salt Objective Learn how to do a gravity filtration in order to find the percent composition of a compound. Use the percent composition to find the empirical formula of a compound. In addition, to acquire information about hydrated compounds. These are valuable concepts for future experiments involving determining compound makeups and masses. Using experimental data collected from the lab the empirical formula of a compound can be found. The percent composition of the different components must be found in the laboratory. These percentages can determine the empirical formula for the compound. The resulting formula can support other experimental results, or disprove the hypothesized identity of the substance. Mass % of A = (Mass of A)/(total mass of substance A) x 100 A is one constituent of the substance. Since mass percent is an intensive property it is
