Experiment 3 . Measuring Mass and Density Measuring Mass 3 and Density Procedure A. Measuring Mass of Solids 1. Using an electronic balance, record the mass in grams of two different small beakers, a rubber stop- per, a watch glass, and an unknown metal cylinder. Three decimal places should be recorded using an electronic balance (i.e., to the thousandth of a gram). The total number of significant figures will vary depending upon the object being measured, but all measurements must have three decimal places when an electronic balance is used. Your instructor will demonstrate the use of an electronic balance. 200 m Hayden-McNeil, LLC - 100 - 50 Beaker Watch glass 2.
