Introduction: This experiment consists of forming a metal sulfide, determining exactly how much sulfur was used and determining the empirical formula of the created metal sulfide using the molar masses of the metal and sulfur. This experiment deepens our understanding of the empirical formula and the formulas of compounds in general, which we have been discussing in lectures. In order to perform this experiment, it is necessary to know how to accurately weigh masses, and know how to correctly use the Bunsen burners. Procedure: The procedure followed was that given in the lab manual: Sprague, Alexander, Padolik & Steffel, Laboratory Experiments for First Year Chemistry, 3 rd ed. pp. 2-1 to 2-4, except we did not save our products in vials, we just showed them to the TA and then threw them out. Also at the end of the experiment we entered our findings into the computer, which was not instructed in...
