Ryan Cohen Monday, 6-8:50 pm 11/9/08 Ms. Sohn Lab Report The purpose of this lab is to explore the common gas laws and how they apply to ideal gases. Through careful measurement and experimentation, the experiment calculates Molarity and volume of a gas given off by chemical reaction. Ultimately, using Dalton’s Theory of Partial Pressures and the Ideal Gas Laws, the experiment applies such data to calculate the molar volume of a gas at standard temperature and pressure. Part 1 sought to gather data of O 2 (g) released in the decomposition of hydrogen peroxide in order to determine the molar volume of O 2 at STP. The chemical equation for the decomposition of H 2 O 2 goes as follows (FeCl 2 was used as a catalyst): 2H 2 O 2 (l) → 2H 2 O (l) + O 2 (g). The experiment set up a sealed flask “A” where the reaction occurred, connected to a sealed flask “B” filled with water, leading to an open collection beaker, “C.” Essentially, as the H 2 O 2 reacted, the O 2 gas displaced the water in beaker B, forcing an equal volume of water into beaker
