Measuring the Volume of Substances and Objects Using Appropriate Glassware Objective Upon completion of this laboratory exercise, students will be expected to: demonstrate an ability to accurately identify common glassware used for measuring volume. choose glassware of appropriate size and precision for a variety of uses and measurements in a chemistry laboratory. accurately record volume measurements of liquids, regular solids (cubes, rectangular prisms, cylinders, etc.), and solid with irregular shapes using appropriate precision for the chosen glassware. Introduction The accurate measurement of volumes is a skill that is fundamental in the kitchen as well as a chemistry laboratory. In a kitchen, measuring the correct amount of ingredients is important for ensuring a recipe tastes just right; but in a chemistry laboratory, it is integral to many experiments involving the chemical and physical properties of matter such as density determinations, chemical reactions, and dilution of reagents, among others. In a kitchen, volume is measured using tools specialized for different applications and amounts; for example, large and small measuring cups and measuring spoons are used to measure relatively consistent amounts of ingredients. In much the same way, chemists use a variety of tools to measure volumes of chemicals in the laboratory. While some glassware in a chemistry laboratory such as standard pipet, beakers, and Erlenmeyer flasks (Figure 1) tend to be valued for their versatility, others such as volumetric pipets, volumetric flasks, burets, and graduated cylinders (Figure 2) are valued for more specific measurements. A. B. Figure 1. Laboratory tools for approximate measurements of volume: A. a plastic pipet, B. a beaker, and C. an Erlenmeyer Flask. Here we will describe some standard types of chemistry glassware and how to accurately use them to measure volume; we will learn which types of glassware should be used for certain types of tasks. Once we have learned how to identify and use appropriate glassware, we will measure the volumes of some
