April Moore sec 519 Experiment 1 Lab Report The amount of water that each volumetric material contains varies slightly. Based on the results from the class, the weight of water contained in a 50 mL beaker ranges from 27.3888-29.5680. This slight difference affects the accuracy of each container in a similar way. The top loader balance is more precise because it rounds to the hundredths place allowing the mass of the water from different containers to be closer to each other. When you are looking for an accurate measure it is better to use the analytical balance. A group of data from a top loader balance is not accurate because the measures are rounded. A top loader balance measures to the ten thousandths giving a more accurate answer. Based on the class data the most accurate glassware to most precise glassware was 4.9544 mL in 5mL pipette with .912 % error, 29.784 mL 50mL burette .7153 % error, 8.1039 mL 10mL pipette 1.29 % error, 29.1089 mL 50 mL graduated 2.97 % error, 29.7894 50 mL beaker 4.4233 % error, 42.4222 125 ml
