How do you read a 50 mL graduated cylinder? With a 50-mL graduated cylinder, read and record the volume to the nearest 0.1 mL. The 10-mL graduated cylinder scale is read to the nearest 0.01 mL and the 500-mL graduated cylinder scale is read to the nearest milliliter (1 mL).
How do you correctly read a graduated cylinder?
Use the bottom of the meniscus to determine the volume in the 10mL graduated cylinder. Furthermore, how do you read a graduated cylinder? To correctly read a graduated cylinder, the surface at the center of the meniscus must be read, not the top of the ring of liquid clinging to the wall of the graduated cylinder.
Which is the most accurate way to read a graduated cylinder?
The 10-mL graduated cylinders are always read to 2 decimal places (e.g. 5.50 mL) and the 100-mL graduated cylinders are always read to 1 decimal place (e.g. 50.5 mL). so that the line at the bottom of the meniscus gives the most accurate reading. Moreover, why is the graduated cylinder more accurate?
What is the proper technique to read a graduated cylinder?
Use the following guidelines to help make your scientific drawing as clear as possible:
- Use a pencil.
- Title your drawing.
- Be sure that the size of the drawing is proportional to the way it appears in the field of view.
- Use a ruler to draw label lines.
- Do not use arrows for label lines.
- Be sure that label lines point to the center of the structure being labeled.
- Print all labels horizontally.
What are the rules for reading a graduated cylinder?
To correctly read a graduated cylinder, the surface at the center of the meniscus must be read, not the top of the ring of liquid clinging to the wall of the graduated cylinder. For most liquids, this “center” will be the lowest point of the meniscus.

How many significant figures are in 50 mL graduated cylinder?
two sig figsIn the case of the glassware used in general chemistry lab, both the 10mL volumetric pipette and 50mL volumetric flask will have two sig figs after the decimal point (i.e. 10.00mL and 50.00mL).
When using the 50 mL graduated cylinder how many decimal places should be recorded?
2 decimal placesNow dispense approximately 12 mL from the burette into the clean dry 50 mL beaker. Record the final volume of the burette as final burette volume to 2 decimal places.
How do you read a 25 mL graduated cylinder?
In the 25-mL graduated cylinder, first subtract 25 mL - 20 mL = 5 mL. Next, count that ten intervals are between the labeled graduations. Therefore, the scale increment is 5 mL/10 graduations = 0.5 mL/graduation.
What are the lines on a graduated cylinder?
A graduated cylinder, also known as a measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.
How many decimal places do you read a 50 mL burette?
Burets can be used to measure volumes up to 50 mL with both precision and accuracy (see figure 1). Because they are calibrated to the tenth of one mL, volumes can be recorded to the hundredth decimal place.

What is a graduated cylinder?
A graduated cylinder is basically a test tube with volume markings. It has a spout for pouring and a built-in base so it can stand upright on its own. They measure volumes accurately if the reading technique is correct. The video below helps demonstrate this.
What should the bottom of a meniscus line up with?
The bottom of the meniscus should line up with the cylinder’s calibration lines for an accurate reading. The video shows a 100 ml graduated cylinder in use where the viewing angle is level. This is compared to reading slightly above and below which is wrong.
