Rasmussen 2 A. Research Question: What is the volume of one mole of gas at standard temperature and pressure? B. Theoretical Approach: a. By mixing the chemicals KClO3 and MnO2 and burning them in a closed apparatus oxygen gas will be formed. The MnO2 did not have an outcome on the overall oxygen released; it just acted as a catalyst. Since the masses of these two chemicals (and their molecular mass) are known, I was able to determine the number of moles reacted. Since you are able to set up a balanced equation with Oxygen gas as a product, and KClO3 as a reactant, it is possible to determine how many moles of Oxygen gas will be created. In a closed apparatus the Oxygen displaced “x amount” of mL of liquid from the system. This amount of liquid displaced is the volume of Oxygen gas created. Then using simple mathematics it was possible to find out how much space an entire mole of oxygen would have displaced. C. Observations:
