    Theory The first experiment focused on the concept of errors and uncertainties that are obtained during measurements. For an experiment to be successful, especially those that involve measurements, the number of significant figures must be known. Significant figures are the digits required to express a measured quantity and thus reflect the accuracy of the measurement. Uncertainty is defined as the smallest increment that can be measured and is defined by the instrument used. An error is defined...

    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...
