Unformatted text preview: William Pittman SI D: 817000368 9/13/2007 Conservation Laws Summary- In this experiment, liquids in 5mL increments were added to certain vessels and then weighed after each addition. This was performed with two different liquids: distilled water and acetone. The first part of the experiment (Part A) consisted of adding 5mL of distilled water and then weighing after each addition. This was repeated using acetone as well. Using the data obtained from this, the average volume of the pipette and the density of acetone was found using calculations from the distilled water part of the experiment. Part B consisted of adding 5mL of water to 5mL and also 5mLof acetone to 5mL of water. Each of these additions was performed 3 times while one of the trials of acetone to water was reversed in order of addition. The major results of this were that when each of the liquids was added, mass and volume were conserved. All Numbers obtained are included in the following tables while important information is highlighted. Results – Part A - Water.
