1. 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. 3. Record the new volume of the water. 4.

12 lip 2023 · 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.
If you look at a 10mL graduated cylinder, for example, the smallest graduation is tenth of a milliliter (0.1mL). That means when you read the volume, you can estimate to the hundredths place (0.01mL). Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder.
Partially filled 10 mL, 100 mL and 1000 mL graduated cylinders will be placed in the front of the classroom. Read these cylinders to the correct number of significant figures.
15 sty 2022 · The correct method to determine uncertainty is called volumetric calibration. Take for example a $\pu{100 mL}$ cylinder. You would measure, for example, $\pu{60 mL}$ of water or any other solvent of choice. The liquid would be transferred to a weighing vessel and the exact mass would be measured. The process would be repeated at least 10 times.
