IB Chemistry - Practical Report Name: Chris Bolton Partner: Jamie Gearing Date(s) Conducted: 18/07/04 Topic: Application of Gas Laws Experiment: Determination of the Value of the Gas Constant and the Molar Volume of Oxygen at STP Aim: To experimentally determine the value of (I) the gas constant and (II) the molar volume of oxygen at ?SLC, and therefore to determine the molar volume of an ideal gas at STP. Hypothesis: The empirically determined values for the gas constant and the molar volume of oxygen at SLC (extrapolated to STP) should roughly approximate literature values for the gas constant (8.31 J.K-1.mol-1) and molar volume of an ideal gas (22.4 dm3.mol-1) at STP respectively, to the degrees of accuracy permitted by experimental procedure. Apparatus: MATERIALS: ? 2 grams potassium permanganate (KMnO4(s)) GENERAL: Test tube with a one-holed bung in it, retort stand, boss and clamp, rubber tubing, glass wool, 100 cm3 gas syringe, glass tubing, spatula, electronic balance SAFETY: Lab coat and safety glasses to...
