Abstract:
This lab contains four different experiments. All four experiments focus on proper laboratory techniques. The reasoning behind this lab was to become familiar with lab equipment, the proper usage of lab equipment, and how to correctly take data and notes. The first experiment of this lab was to determine the volume of water in various types of equipment. The second experiment was to measure the different masses of pennies from pre and post 1982. The third experiment was to calibrate and measure the volume of a 5-ml pipette. The last and final experiment of this lab was to record the temperature of boiling and frozen water and to calculate the true boiling point of water at the given atmospheric pressure.
Introduction: Laboratory 1 is deigned to prepare students for further labs. Lab 1 allows students to practice their skills at reading data from various types of equipment. It teaches students how to use a Bunsen burner, graduated cylinders, burettes, Erlenmeyer flasks, and a balance. Besides just allowing the users to gain experience using different types of equipment, this lab will improve the users performance in solving problems of density, volume, mass, average, and deviation. In order to solve for density, volume, or mass the following equation can be used: D = M/V. The average is found by adding all of the products together and then dividing the sum by the number of products and deviation is found by taking the highest product and subtracting that by the smallest product. I am sure that the methods of this lab will be used again in another lab.
Experimental Procedure:
Procedure 1: In procedure 1 the level of water must be recorded for four different pieces of equipment. The four pieces of equipment are a 100-mL graduated cylinder, 10- mL graduated cylinder, 50- mL burette, and a 250-mL Erlenmeyer flask. When reading the levels of
