Experiment 2: Compound Stoichiometry Jonathan M. Brate October 27 th , 2008 Monday 2:00-5:00 Andrea Kravats Introduction: The objective of Experiment 2 was to practice measuring materials and use those measurements to calculate the moles of each element used and thereby find the mole ratio and empirical formula of the elements and determine if the amount of reactant effects the resulting compound’s empirical formula. In order to do this, copper and sulfur were weighed individually, then again once they reacted by being heated inside a crucible over top of a burner, allowing time

for the materials to cool to insure an accurate measurement of the weight. This pertains to Chemistry 101 Lecture because in chapter 2 the book tells how to find moles of a certain mass of a substance, how to find the mole ratios of two substances, and how to deduce the mole ratios into empirical formulas. Experimental Procedure: The procedure followed was that given in the lab manual: Sprague,
