The questions may be answered in any order, so adjust your wor k according to the availability of the lab equipment. (Subtract the mass of the empty graduated cylinder from the mass of the graduated cylinder with liquid.) Procedure (1): Lab Table If the dimensions of the object being measured are much larger than the precision of the measuring instrument (100 times or more), the instrument is considered very adequate for the measurement and will give fairly "precise" results. PDF. Use the electronic balance in the weigh room to determine the mass of the same Erlenmeyer flask. Precision of Measurements Density of a Metal Cylinder ... A measurement reading usually has one more significant figure than the least c ount reading of ... that the strip is closer to 41.6 cm than it is to 41.7 cm and report the length to be 41.64 cm or 0.4164 m. 2 Triple-beam balance. This may be neglected at the moment, though, as this ... HORIZONTAL DISTANCE MEASUREMENT. Lab report templates are documents which are written to explain, describe and analyze a laboratory experiment. Using this calculation, the precision of the scale can be represented by giving the mean, plus or minus the standard deviation. Since the digital display of the balance is limited to 2 decimal places, you could report … Lab 1: Precision Measurements September 1, 2016 Objectives Experiment 1: Density of Metal Cylinders The 52010 Measurement Lab 1-3 (i) Name_____ Exercise #1 — Basic Metric System Report Sheets The Metric System is a standardized method for defining length, volume and weight. Download PDF. Essay Example on Precision Measurement Lab Report. When reading non-electronic devices such as rulers, thermometers, and glassware, the general rule of thumb is to "read between the lines"! ... that the relative precision computed—38—is not within the 1 1 range of accepted precision for measuring distance by pacing, which is from 200 to500. Surveying Lab Report 1. Make measurements to the nearest 1/10 of a millimeter using a meter stick. Free PDF. For example, if in lab you obtain a weight measurement of 3.2 kg for a given substance, but the actual or known weight is 10 kg, then your measurement is not accurate. Meanwhile, the beaker ended up being the least accurate and precise. 1.0 ABSTRACT Viscosity is one of the properties to describe the “fluidity” of fluid. 19 Full PDFs related to this paper.
