Report average and standard deviation with appropriate number of significant figures. What is the average measured volume of the volumetric flask? What is the standard deviation of the volumetric flask measurement? What is the average measured volume of the beaker? What is the standard deviation of the beaker measurement? Which piece of glassware delivers the more accurate volume?

beaker or volumetric flask

In the laboratory, you will be using calibrated glassware to prepare solutions. Calibrated glassware is manufactured to deliver ("TD") or to contain ("TC") a specific volume of liquid at a certain temperature, usually 20C. Calibrated glassware is identified by a fiduciary mark around the neck of the glassware piece. Given the following pieces of glassware and their respective delivered volumes, determine which piece of glassware delivers the more accurate volume. Use the table of water volumes of 1.000g vs. temperature to find the volume of liquid delivered. The mass of the empty volumetric flask is 34.0169g. The mass of the empty beaker is 50.0681g. The air temperature is 22C. The following measurements were made with six replicate samples for each container
