17 cze 2023 · If you look at a 10 mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1 mL). That means when you read the volume, you can estimate to the hundredths place (0.01 mL).
CHEMISTRY 11 – EXPERIMENTAL UNCERTAINTY OF APPARATUS WORKSHEET. (1) Record the values for the experimental uncertainty encountered in using the following apparatus: Apparatus. Difference between numbered divisions. # of unnumbered subdivisions between numbered divisions.
Use the 10 mL graduated cylinder, which will be accurate to two significant figures. Mathematical operations are carried out using all the digits given and then rounding the final result to the correct number of significant figures to obtain a reasonable answer.
Using a 100-mL graduated cylinder, fill the graduated cylinder to approximately 50 mL with tap water and record the volume to the correct number of significant figures. 2. Take the same metal object that you just measured for volume and carefully place the object in the graduated cylinder.
Learning Objectives. By the end of this section, you will be able to: Define accuracy and precision. Distinguish exact and uncertain numbers. Correctly represent uncertainty in quantities using significant figures. Apply proper rounding rules to computed quantities.
12 cze 2008 · Uncertainties for Volumetric Glassware. Volumetric glassware, such as pipettes, burettes, and flasks, is required when performing any analytical determinations. This page provides a table of typical uncertainty values for the calibrated volume of such glassware.
Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder. Since the smallest division (graduation) is a tenth of a milliliter, we can estimate to a hundredth of a milliliter (0.01). 3.87mL. Portion of a 10mL graduated cylinder.
