This is a lab report concerning essays Objective: To become familiar with various types of laboratory equipment Materials and Methods/Procedures: A 10ml pipette was used to pipette 5ml of water 4 times into a 50 ml graduated cylinder, and the results were measured. Next, a 50 ml graduated cylinder was filled to the 50 ml mark twice and the contents were poured into a dry 100 ml volumetric flask, and a 100 ml graduated cylinder was filled to the 100 ml mark and the contents were poured into a dry 100 ml volumetric flask. The results of the 100 ml experiments were then compared. A ruler was used to measure the side of a cube in inches and the number was converted into centimeters, millimeters and meters. A triple beam balance was used to weigh an item, the results were converted to grams, milligrams and kilograms. An empty 100 ml beaker was weighed and then 50 ml of water was added, and the beaker was weighed again. The beaker's weight was subtracted to obtain the weight of the water. The procedure was repeated with a 25 ml beaker and 10 ml of 200 proof ethyl alcohol. 50 ml was converted to microliter, deciliter and liter. Six stoppers of similar size were weighed individually and the Results: The results of the pipette procedure showed the volume in the graduated cylinder was 20 ml and there was not a difference in the expected result. The procedure with 100 ml of water proved that the volume of both experiments was the same- 100 ml. The measurement of the side of the cube was .5 inches, 1.27 cm, 12.7 mm and 00127 meters. The weight of the object was 15.852 g, 15851 mg, and 0.015852 kg. The weight of the beaker was 49.49 g, the beaker and water weighed 99.93 g, resulting in the water weighing 50.440 g. The density of the water was 440 g/ml. The weight of the next beaker was 30.059 g, the beaker and alcohol weighed 37.825 g, with the alcohol alone weighing 7.226 g. and havin ...
