Density and Treatment of DataKatelynn TruongChemistry 1A Summer2016 June 29, 2016Objective/PurposeThe purpose of this experiment is to understand how to perform statistical analysis ofexperimental data. We will determine the density of a solid, calibrate the volume of apipette and use the calibrated pipette to determine the density of an unknown liquid.Theoreticalܣݒ݁ݎܽ݃݁ ൌݔଵ ݔଶ ݔଷ3ܴܽ݊݃݁ ൌ ܹ ൌ ൫ݔ௦௧െ ݔ௦௦௧൯ܦ݁ݒ݅ܽݐ݅݊ ൌ ߜଵൌ ݔ̅ െ ݔଵܣݒ݁ݎܽ݃݁ ܦ݁ݒ݅ܽݐ݅݊ ൌߜ̅ൌ|ߜଵ| |ߜଶ| |ߜଷ|3ܵݐܽ݊݀ܽݎ݀ ܦ݁ݒ݅ܽݐ݅݊ ൌݏ ൌඨߜଵଶ ߜଶଶ ߜଷଶ3 െ 1ܦ݁݊ݏ݅ݐݕൌܸ݉Pre-lab Sections:Experimental Procedure and MSDS InformationDataTable 1:Determination of the Density of a metalTrial 1Trial 2Trial 3Mass of solid (g)48.13448.8248.134Volume of water and solid(mL)56.556.055.9Volume of Water (mL)50.050.050.0Volume of Solid (g)6.56.05.9Density of Solid (g/mL)7.48.08.2
