, polymethylpentene.
Which is more accurate 10mL or 50ml graduated cylinder?
Answer Expert Verified
The cylinder with the greater precision is the 10 ml graduated cylinder
. The 50 ml graduated cylinder on the other hand has marks for every 1 ml, this graduation will only allow the user to record measurement up to one significant figure.
Why is a 10mL graduated cylinder more accurate?
Why is a 10ml graduated cylinder more accurate? Well,
graduated cylinders have more markings
, and are thus designed to be more accurate… Examine this graduated cylinder. It has markings every 1 mL , so you can make measurements to the 1st decimal place as the uncertain digit.
Why is a graduated cylinder more accurate?
Why is a graduated cylinder more accurate than a beaker? … The accuracy of a graduated cylinder
is higher because the graduations on the cylinder make it easier to more precisely fill, pour, measure, and read the amount of liquid contained within
.
What is the most accurate graduated cylinder?
The tolerance on graduated cylinders is about 1%.
Volumetric flasks, burets and pipets
are the most accurate with tolerances of less than 0.2%.
Why is it better to use a 25 mL graduated cylinder?
Explanation: A marble is not a very large object,
so a smaller graduated cylinder is a better choice
. A 100 milliliter graduated cylinder is not needed to measure the volume of a small marble, so a 25 milliliter graduated cylinder is the best option.
What is more accurate a balance or graduated cylinder?
Graduated cylinders
are generally more accurate and precise than laboratory flasks and beakers, but they should not be used to perform volumetric analysis; volumetric glassware, such as a volumetric flask or volumetric pipette, should be used, as it is even more accurate and precise.
How accurate are graduated cylinders?
Graduated cylinders are designed for accurate measurements of liquids with a much smaller error than beakers. They are thinner than a beaker, have many more graduation marks, and are designed to be
within 0.5-1% error
.
What is the uncertainty of a 50 mL graduated cylinder?
| Glassware Volume in mL ± Uncertainty in mL | Buret 50.00 100.00 0.05 0.10 | Erlenmeyer flasks 100 250 5 10 | Beaker 50 100 5 5 | Graduated cylinder 10.0 100.0 0.1 0.5 |

How accurate is a 100 mL graduated cylinder?
This graduated cylinder has a capacity of 100 ml with graduations marked every 1.0 ml and it has an accuracy of
± 1.0 ml at 20°C
. Approximately 25 cm tall and 3 cm in diameter.
Why would you use a graduated cylinder?
Graduated cylinders are long, slender
vessels used for measuring the volumes of liquids
. They are not intended for mixing, stirring, heating, or weighing. Graduated cylinders commonly range in size from 5 mL to 500 mL.
Is a graduated cylinder more accurate than a volumetric flask?
The
volumetric flask
had the lowest percent error (0.3%), so it is the most accurate. The graduated cylinder and beaker were similar in percent error (2.2% and 3.5% respectively). Both were small, so they are fairly accurate. The flask had the highest percent error (17.4%), so it is the least accurate.
What is the first thing you have to determine when using a graduated cylinder?
Place the graduated cylinder on a flat surface and
view the height of the liquid in the cylinder with your eyes directly level with the
liquid. The liquid will tend to curve downward. This curve is called the meniscus. Always read the measurement at the bottom of the meniscus.
When would you use a beaker instead of a graduated cylinder?
Both graduated cylinders and beakers are pieces of laboratory glassware that have a specific function. Graduated cylinders typically are more accurate at reading the volumes of the liquid inside. Beakers are
better for stirring and mixing liquids
.
Why is burette more accurate than graduated cylinder?
Why is a graduated cylinder more accurate than a beaker? A graduated cylinder is used routinely for measuring volume and is considered more accurate than a beaker
because of the permanently-marked incremental graduations incorporated in the clear cylinder
.
Why use a volumetric flask instead of a graduated cylinder?
The volumetric flask is
used for measuring accurate volumes of liquid materials for laboratory experiments
. They are favored when available because they are more accurate than graduated cylinders and beakers, which are other pieces of equipment that are used to measure liquids.
