• ##### Experiment 2: a Memo from Corporate Accuracy and Precision of “Volumetric” Glassware

A MEMO FROM CORPORATE Accuracy and Precision of “Volumetric” glassware Jazet Nell Guimsop Objectives: In this laboratory experiment, the accuracy and precision of glassware made by a company manufacturing them will be assessed. This will be done by taking different volumes of water using a 10 mL graduated pipet, a 50 mL graduated buret, a 10 mL graduated cylinder, and a 50 mL graduated cylinder. After weighing each volume, we used the density of water at our room temperature to calculate...
