-1Chemistry 101 Lab Report - Experiment 1 Accuracy - Precision - Solution - Dilution Introduction: Experiment 1 was over solutions, dilutions, and the differences between accuracy and precision. It also covered the fundamental skills for properly using glassware and other chemistry apparatus. We explored the scientific method, random and systematic errors, significant figures, standard deviation, and mean. We also gained knowledge of the different types of glassware found in the lab along with the balances and thermometers. In part one of the experiment we tested various types glassware and practiced using the top-loader and analytical balance. We weighed different pieces of glassware without water and then again with water to test the accuracy of each piece of glassware. As a lab group, we were able to use such instruments like the graduated cylinder, serological pipette, buret, and the Erlenmeyer flask. Data was collected from the entire class and entered into Excel. In part two of the experiment we dug deeper into the roots of chemistry by testing various solutions and dilutions. We prepared a sodium chloride stock solution and prepared different 12 mL concentrations. This part of the experiment helped us to understand more about accuracy and precision. We also learned
